- Abstract
- We report on a novel method of a fabrication of a ZnS buffer layer for an application of Cu(In, Ga)Se2 (CIGS) solar cells. The ZnS thin film was prepared by a sulfurization of a sputtered Zn film using a sulfur cracker. The structural and optical properties of the ZnS films and the photovoltaic performance of the ZnS-employed CIGS solar cells were investigated. The thin ZnS film played a sufficient role as a buffer layer achieving the power conversion efficiency of 10.5%. © 2013 IEEE.
