Chemical resistance properties of molybdenum back electrodes used in non-vacuum Cu(In,Ga)Se 2 thin film solar cell

Research output: Contribution to journalArticle

Abstract

The first step in fabricating copper-indium-gallium-diselenium solar cells (CIGS) is to deposit a thin film of molybdenum (to serve as the back electrode), on a glass substrate. Prior to depositing the absorption layer, the surface of the Mo back electrode is cleaned with acetone; however, this may cause the electrode to separate from the substrate. The aim of this study was to discover the specific cause of the separation, and arrive at a solution to correct this behavior. The result is a thin film comprising crystals of different sizes and orientations. Optimal results were obtained when the bi-layer Mo electrode was deposited on a substrate heated to a temperature of 373 K.
