Reliability of Low Cost Cu2S/CdS Solar Cells for Large Scale Conversion of Solar to Electrical Energy
Large scale conversion of solar to electrical energy at low cost is possible using high efficiency, high reliability Cu2S/Cds solar cells. Low cost fabrication involves relatively simple processes consuming small amounts of material. Accelerated life tests give extrapolated lifetime in excess of twenty years. The probable decay mechanisms are thermal diffusion, formation of recombination centers, and voltage induced decomposition.
