Comparison Between Al- and B-Doped Zno Window Layers For CuInSe2Thin Film Solar Cells

Abstract
A comparative study of several properties of ZnO:Al and ZnO:B films grown by magnetron sputtering has been performed. The influence of these window layers on device performance has also been investigated. Sputter-deposited ZnO:B films were used for the first time as a window material of CIS thin film solar cells. The short circuit current was improved by replacing ZnO:Al with ZnO:B window layers. A discussion of the issues relating to ZnO window layers for improving cell performance is presented.
