Greg Ashley, COO of Solar Frontier, describes the company’s copper-indium-selenide (CIS) thin-film photovoltaics technology. He speaks with senior technical editor Debra Vogler.
The company’s roadmap for photovoltaic cell and module efficiency works out as follows: currently, the cell efficiency and module efficiency are >16% (1 × 1ft cell), and 11.5%, respectively; by 2011, module efficiency is expected to be close to 12.5%, and by the end of 2013, the company expects to achieve a module efficiency of 13%; and by 2014, 14% or higher.
According to Ashley, these numbers match the polycrystalline solar cell efficiencies but at a much higher volume, predictable cost, predictable deliveries, and predictable performance. The company will be turning out ~1GW of capacity every two years.
