ISET is a private California Corporation with a wide range of expertise in next generation thin film solar electric products and systems. ISET has carried out extensive R&D work in the area of photovoltaic’s (PV) – the technology for direct conversion of sunlight into electricity. Major research breakthroughs involve development of novel, low-cost manufacturing alternatives for fabrication of “printable” high efficiency solar cells which are unique to the entire solar energy industry.

ISET has developed an ink-based process for manufacturing thin-film CIGS solar cells and modules on both rigid and flexible lightweight substrates. This patented technology offers fundamental improvements over existing solutions for both terrestrial and space power applications. Current development efforts deliver a prospect for commercial application that will produce thin-film PV modules for a cost of less than $1.00/watt.

ISET offers technology transfer, customized PV products, PV system design services for both stand-alone and grid-connected systems and general consulting services relating to PV technologies.

Company Information

International Solar Electric Technology (ISET) was established as a California corporation on March 24, 1985 for the purpose of performing R&D and product development in the field of thin film materials and photovoltaic (solar) cells. During the last 19 years, ISET has carried out extensive R&D work in thin film technologies.

The company was originally established by Dr. Vijay K. Kapur, Dr. Bulent M. Basol and Mr. Eric Tseng with the objective of developing low cost materials and processes for manufacturing PV modules. Since 1985, ISET has received nearly $15 million in funding from federal, state agencies, California State and private corporations. ISET’s Laboratories and Manufacturing facilities are housed in a 23,000 ft2 facility at 20600 Plummer St., in Chatsworth, California.

Founding Members

Dr. Vijay K. Kapur, President
He received a Ph.D. degree in Physical Chemistry from the University of Pennsylvania in 1976 and subsequently received an MBA degree from UCLA in 1992. Prior to starting ISET, Dr. Kapur was Director of Applied Research at ARCO Solar (now Shell Solar) from 1979 -1984 and he worked at Stanford Research Institute (SRI International) from 1976 to 1979. He has more than 30 years of working experience in the PV field.
