Thin-film CdS/CdTe solar cell with 15.8% efficiency

Abstract
This letter describes the fabrication and characteristics of high-efficiency thin-film CdS/CdTe heterojunction solar cells. CdS films have been prepared by chemical bath deposition and p-CdTe films have been deposited by close-spaced sublimation. A CdS/CdTe solar cell of greater than 1 cm2 area with an AM1.5 efficiency of 15.8% is reported.
