QUOTE Photovoltaic cells suffer from a drop in efficiency with the rise in temperature due to increased resistance. UNQUOTE The statement is false. The decrease in efficiency is mainly due to minority carrier increase. The electron hole pair from minority carriers have a lower kinetic then the majority carriers which can cross the junction. This carrier swap degrades the electron mean free path resulting in less charge accumulate at the receiver. Resistance Temperature Coefficient taken over the range of operation of a semiconductor has a minimal impact on overall efficiency.

Preferably an expert in semiconductors should review this article for validity.
