Paper Abstract

There has been what has appeared to be an insurmountable barrier holding back the progress of amorphous photovoltaics. Conventional amorphous photovoltaic cells, despite claims of initial efficiency, lack stability to the point of reducing their efficiency to no more than 5-6%. We will describe how true efficiencies of 13% and over are now practical, showing virtually no degradation. We have now developed materials that can bring efficiencies to 20%. Equally important, by the use of a proprietary continuous web production process, multilayered cells are produced with very high yields. Based upon several years of production experience, we can now realistically discuss how amorphous photovoltaics can become competitive to conventional fuels.
