Abengoa Solar

Abengoa Solar

History of Abengoa Solar

Abengoa began its involvement in the development of solar technologies in 1984 with the construction of the Solar Almeria Platform in Spain. The company supplied heliostats and glass facets and worked on the construction of the Cesa Tower. Later, in 1987, Abengoa supplied the facets for the heliostat field of the Weizmann Institute in Israel.
This initial work was undertaken by the Abengoa company, Inabensa as part of its construction department.
In the 1990’s, a new department was created devoted to solar R&D projects. In 1983, Abengoa Solar IST (then Industrial Solar Technology) was founded by Ken May with the purpose of developing trough technology that was economically feasible for commercial and industrial applications.
The 90s: Concetrated Solar Power and Photovoltaic R&D Projects

In 1993, Abengoa built Toledo PV, a 1MW turn-key photovoltaic plant, that is owned by Union Fenosa, Endesa and RWE. The project was built with a subsidy from the European Union.
In 1994, several tower R&D projects were initiated. These projects were partially subsidized by the European Union under Framework Programs IV, V and V. R&D focused on different types of receivers. One of the projects, Solgas, focused on steam generation while the other, Colon Star, focused on electricity generation. Between 1995 and 2000, several R&D projects involving troughs began under by the EU Framework Program s IV and V. The following are highlights of the late 90’s R&D projects.

* The Theseus Project: The Theseus Project studied the feasibility of a parabolic trough plant in Greece.

* Eurotrough: Abengoa Solar was one of the leaders in developing the Eurotrough. The purpose of this project was to develop a parabolic trough with improved optical efficiency, and better manufacturing and assembly processes compared to existing designs.

* DISS: A research project investigating the direct generation of steam in the trough receiver. The research goal was a major technical advance leading to a 30% increase in the efficiency of parabolic trough electricity generation.

In the 1990’s Abengoa Solar also collaborated on dish-Stirling projects involving the production of the Eurodish and Envirodish.

Abengoa Solar worked on concentrated photovoltaic projects. The outcome was the low-concentration dishes (Sevilla PV) now installed at the Sanlucar Solar Platform.

During this time, Abengoa Solar IST worked with some of the world’s best labs and institutions to improve and install solar trough systems for industrial and commercial applications.

2004 to Present: Transition from R&D to Commercial Plant Construction

Based on the economic and technical foundation provided by investments in R&D, Abengoa Solar has transitioned into a pioneer in the construction of commercial CSP and PV plants.

In 2007, Abengoa Solar inaugurated the world’s first commercial solar tower plant, the 11 MW, PS10, and the world’s largest low-concentration PV plant ( Sevilla PV, 1.2 MW). These two plants are part of the Sanlucar Platform, which when complete in 2013 will have a total capacity of 300 MW. Such output can supply the needs of 18,000 households in Seville, while eliminating 600,000 tons of CO2 per year. Besides the Sanlucar Platform, Abengoa Solar is building additional plants in Spain, the USA, Algeria and Morocco.

Abengoa Solar New Technologies (NT) is the R&D company of Abengoa Solar in Spain. Abengoa Solar NT collaborates with institutions such as NREL, Ciemat and Fraunhofer, as well as research universities to develop CSP and PV technology. In addition, Abengoa Solar NT performs internally-funded R&D to develop new proprietary knowledge aimed at improving performance and reducing the cost of solar technology.


Operating Principle

Photovoltaic (PV) cells use semiconductors to produce electricity. The cell absorbs solar radiation, which excites the electrons inside the cell. A semiconductor must have at least two electric fields. When an electron excited by solar energy leaves its electric field, it seeks to return to its original electric field. In order to do so, it must pass through an external circuit, producing electricity. This is referred to as the photovoltaic effect.

PV technology

The following are the primary components of PV technology.

  • Optics: Different optical elements, such as mirrors and Fresnel lenses, are used to concentrate solar radiation onto a point where a PV cell is located.
  • Photovoltaic Cell: The photovoltaic cell is the semiconductor used to produce the photovoltaic effect.
  • Inverter: Since the photovoltaic effect produces direct current (DC), an inverter must be used to change it to alternating current (AC).

Types of Photovoltaic Cells

There are two predominate PV systems on the market. Each has their own pros and cons regarding application, efficiency, and cost.

1 Crystallized Silicon (~200 µm)

A double layer antireflection coating is used to reduce reflection losses on the front surface of crystalline silicon wafers. The wafers are about 400 µm thick to ensure near-complete absorption of all photons having energy greater than the band gap. At the bottom of the wafer, a SiO2 layer is inserted between the wafer and the aluminum backing to achieve reflectance back toward the cell.

  • Single-Crystalline Si
    The semiconductors of most PV cells are made from single-crystalline Si. This requires highly purified silicon to be crystallized into ingots. The ingots are then sliced into thin wafers to make an individual PV cell.
  • Polycrystalline Si
    Polycrystalline Si cells are produced in a way very similar to single-crystalline cells. The primary difference is that silicon of less purity is used for polycrystalline cells. The result is reduced cost and increased ease of production, but a loss of efficiency.
  • Ribbon Si
    Ribbon type PV cells are produced in a similar fashion to single- and polycrystalline silicon cells. The primary difference is that a ribbon is grown from molten silicon instead of an ingot. These cells often have a prismatic rainbow appearance due to their antireflective coating.

Ribbon Si

Thin film (~5 µm):

Thin film semiconductor technology may not be as efficient as traditional semiconductor technology, but its light weight and low cost make it an ideal solution for certain applications.

Amorphous Si

  • Amorphous Si
    Unlike crystalline semiconductors which have a band gap of 1.1 eV, by manipulating the alloy of amorphous silicon semiconductors the band gap energy can be tuned between 1.1 eV and 1.75 eV. Additionally, because they have a much greater absorbance than crystalline silicon, amorphous silicon semiconductors can be much thinner (less than 1 µm). Although amorphous Si cells can be manufactured at low temperatures (200-500 C) and at low costs, a major drawback is their light-induced degradation.

Amorphous Si

3 Copper Indium Gallium Diselenide Solar Cells

  • 3 Copper Indium Gallium Diselenide Solar Cells (CIS Cu In Se2)(CIGS Cu(InGa)Se2)
    Due to its relatively high efficiency and low material cost, this technology has emerged as one of the most promising thin films. By adjusting the ratio of In to Ga in CIGS cells, the band gap can be tuned between 1.02 eV and 1.68 eV. The absorption elements of CIGS cells are incredibly high, allowing more than 99% of incoming radiation to be absorbed within the first µm of material. Although this technology has a relatively low material cost, the complicated and capital-intensive manufacturing methods remain as significant drawbacks.

CIGS Solar Cell

Cadmium Telluride

  • Cadmium Telluride (TeCd)
    Cadmium Telluride is another thin film technology that has been available longer and undergone more research than any other thin film technology.
    Although there are diverse manufacturing techniques that can be used to produce the films, many of which are promising for large scale production, the cost and potential health concerns remain as drawbacks for this technology.

Cadmium Telluride

  • Micro Si
    Micro silicon cells are expected to surpass the efficiency and performance of amorphous silicon cells and become a competitor with other thin film technologies. The high efficiency and negligible degradation of Micro Si cells has been widely reported.
  • Titanium dioxide (TiO2)
    Instead of the semiconducting materials used in most cells, TiD cells use a dye-impregnated layer of titanium dioxide to generate voltage. Because of their relatively low cost, TiO technology has the potential to significantly reduce the cost of solar cells.
Photovoltaic Concentration

Offers the best efficiency but requires high direct concentration, and is therefore only viable in some geographies.

Fresnel point focus

  • Fresnel point focus (High concentration-GaAs) (GC~500)
    Fresnel point lenses concentrate direct solar radiation onto a focal point. Since Fresnel lens can provide concentration ratios of up to 500, the necessary surface area for PV cells is greatly reduced. Since fewer PV cells are needed, it is possible to use high quality, more expensive materials like Gallium Arsenide for the semiconductors.
    Gallium Arsenide (GaAs) multi-junction semiconductors: Multi-junction semiconductors is a relatively new technology that offers significantly higher efficiencies than traditional, single-junction semiconductors. Each electrical field junction within a semiconductor has only one band gap energy. Incoming solar radiation will either have less energy than the band gap (and therefore will not be used), more energy than the band gap (and therefore some energy will be wasted), or the exact energy as the band gap. By having multiple junctions, GaAs semiconductors are able to utilize more energy from the incoming solar radiation.
  • Fresnel line focus (medium concentration-Si) (GC<500)
    Fresnel line lenses are flat cylindrical lenses that condense or diffuse light in a linear direction. This technology has lower concentration ratios than Fresnel point lenses, so high efficiency silicon semiconductors are used instead of expensive GaAs semiconductors.
  • Low concentration (2-4 times)
    Low concentration (2-4 times) Low concentration technology uses mirrors instead of lenses to concentrate solar radiation. Since the solar radiation is much less condensed, conventional silicon semiconductors are often used because of their affordability.

Founded in 2008, the exclusive focus of ETV Motors Ltd is the research, development and commercialization of critical EV components and their integration into turbine-powered Range-Extended Electric Vehicles (REEVs).

In the third quarter of 2008, ETVM raised a milestone-driven $12M investment led by The Quercus Trust. New York-based 21 Ventures, LLC, a venture capital firm concentrating on the technologies set to dominate the 21st century, is a co-investor.

ETV Motors is a private company based in Herzliya, Israel with research and test facilities at several additional locations. There are presently over 25 researchers and engineers involved in the activity.


ETV Motors Ltd is developing the enabling technologies that will facilitate the future generations of Range-Extended Electric Vehicles (REEVs).

These propulsion platforms will have unparalleled energy efficiencies and ultra-low emission signatures.

The company is engaged in three complementary activities:

Turbine Charger Advanced Battery Test Vehicle

Microturbines produce both heat and electricity on a relatively small scale by means of combustion. In general, they offer advantages compared with other technologies for small scale power generation.

Those advantages over reciprocating engine generators include: a small number of moving parts; compact size; light weight; greater efficiency; lower emissions; and the ability to operate with a range of fuels (eg CNG and bio-fuels). Waste heat recovery may be employed with these systems to reach very high efficiencies.

The majority of a microturbine’s waste heat is contained in its relatively high-temperature exhaust. The combined thermal electrical efficiency of microturbines in cogeneration applications where exhaust heat is utilized reach over 80%.

Turbines offer a high-powered engine in a very small and light package. This is facilitated in part due to the fact that there is no requirement for either water-cooling or exhausts catalytic conversion. However they have a time lag and provide poor fuel efficiencies at low speeds if integrated into conventional propulsion drivetrains.

REEV hybrids utilizing turbines as the on board charger will provide all the advantages as the battery will address the variable power requirements and the turbine will be operating at its “sweet spot”.

In simulation exercises, we have found that the fuel costs for ICE-powered REEVs in typical urban environments will be up to 50% more expensive than those powered by micro-turbine on-board chargers.

ETV Motors has assembled a world class team of microturbine engineers to develop its high efficiency dual power microturbine on board charger. With a track record in stationary power turbines, large and small jet engines and advanced heat exchangers, we are confident that our aggressive performance goals will be achieved in a timely and cost effective manner.

The ETV patent-pending mictroturbine design is expected to outperform the state-of the art microturbines for the following reasons:

  • The ETV mictroturbine will operate on RQL (Rich-Quench-Lean) principles and will have the unique property of achieving optimum efficiency at two operating points. This “dual mode” property will provide a number of degrees of freedom when matching the microturbine to various drive cycles and vehicle categories.
  • Proprietary valving and duct design results in minimal pressure drops
  • Advanced heat exchanger/recuperator resulting in ultra-high thermal efficiencies (>90%) with low pressure drops. (The combined hot and cold pressure drops will be less than 8.5% of maximum cycle pressure)
  • Advanced stator/rotor sealing techniques, resulting in high adiabatic efficiencies.
    Implementation of ceramic regenerative heat exchanger and turbine enabling operation at higher turbine inlet temperatures.

The characteristics of the prototype and production ETV microturbines are presented in the following table.

P1 P2 Production
Power kW 12/45 13/48 20/60
Efficiency % 37-38 38-44 45-50
Weight Kg 120 100-110 100-120
Rotational Speed RPM 80,700 80,700 TBD
Turbine Inlet Temp 0C 975 1,050 1,250-1,350
Recuperator Advanced Metal Ceramic Ceramic
Turbine Metal Metal Ceramic

The P1 turbine, with an efficiency that outperforms the present state of the art by approximately 30%, will be fully functional in Q2 2010.

This new breed of coatable, flexible, plastic photovoltaics can be used in a wide range of applications where traditional photovoltaics cannot compete. Konarka’s technical advances will expand the relevance of solar technology across product lines, as well as across economic divides, providing low cost power wherever it is needed.

Konarka currently employs over 70 staff in the US, Europe, and Asia , with global headquarters in Lowell, Massachusetts, and European operations in Germany, Austria and Switzerland, and a presence in Asia.


Konarka’s Power Plastic® is made using low cost organic materials (organic photovoltaics, or OPV). Such 3rd generation technologies are rapidly emerging to displace 1st and 2nd generation technologies by overcoming their technical limitations and delivering a truly cost-effective renewable power solution.

1st Generation

Crystalline silicon photovoltaic (PV) technology was first developed more than 50 years ago at Bell Labs in New Jersey based on silicon wafers, and is known as 1st generation solar technology. Silicon-based technology is technically proven and reliable, and has succeeded in achieving market penetration, primarily in off-grid remote areas and in grid-connected applications where sufficient subsidies are available to offset its high cost. There are several inherent limitations to this 1st generation, however. Silicon wafers are fragile, making processing difficult and limiting potential applications. The process is very labor and energy intensive, and manufacturing plant capital costs are high, limiting scale-up potential. And because materials represent more than 60% of manufacturing costs and silicon supply is finite, the long term potential for cost reduction is insufficient to deliver broadly affordable energy.

2nd Generation

To simplify manufacturing and reduce costs, a 2nd generation known as thin film technologies was developed. These technologies are typically made by depositing a thin layer of photo-active material onto glass or a flexible substrate, including metal foils, and they commonly use amorphous silicon (a-Si), copper indium gallium diselenide (CIGS), or cadmium telluride (CdTe) as the semiconductor. Thin film PV is less subject to breakage when manufactured on a flexible foil. However, the promise of low cost power has not been realized, and efficiency remains lower than that of 1st generation solar. Some questions also remain about the toxic legacy of the materials, both in manufacturing and at the end of life.

3rd Generation

It has been estimated that 3rd generation solar technologies will achieve higher efficiencies and lower costs than 1st or 2nd generation technologies (Green, M., Third Generation Photovoltaics, Advanced Solar Energy Conversion). Today, the 3rd generation approaches being investigated include dye-sensitized titania solar cells, organic photovoltaics, tandem cells, and materials that generate multiple electron-hole pairs. To maximize performance, Konarka scientists have been involved in research efforts in all of these areas, including novel combinations of these approaches.
