International Solar Electric Technology, or ISET, is a company heavily invested in copper indium gallium selenide (CIGS) photovoltaics. ISET's research  over two decades has been largely funded by grants from the National Renewable Energy Laboratory. Members helped found or worked in many of the more well known CIGS companies, such as Nanosolar, Solopower, Showa, and Honda Soltec. Despite a lack of venture capital, ISET plans to launch a thin film, produced in a new Chatsworth plant with hundreds of megawatts per year capacity after the pilot plant is proven. The company believes they will be able to at first achieve 10% efficient modules sold for $0.65 cents per watt, then 15% efficient for $0.50 per watt, and potentially ultimately as low as $0.40 per watt (a tenth of current prices).
