The generation of electronhyphen;hole pairs in very thin solar cells possessing an optical backhyphen;surface reflector

摘要

It is pointed out that very thin solar cells (1 mgr;m thick or less) as, for example, amorphous silicon or cadmium sulfide cells, possessing a backhyphen;surface reflector should be regarded as Fabryhyphen;Perot cavities as far as the generation of electronhyphen;hole pairs by light is concerned. The generation rate of electronhyphen;hole pairs as a function of distance from the front surface exhibits characteristic interference patterns which are not negligible and must be accounted for in an analysis of the performance of such a cell.
