Abstract

The effect of Na on the structural and electrical properties of CIGS films were studied and their effects on the CIGS/Mo thin film solar cells were investigated. Soda-lime glass and Corning glass were used as substrates to compare the effect of Na diffusion into CIGS film. The resistivity of CIGS films was not changed in the Cu-poor region due to diffusion of Na from soda-lime glass but was mainly determined by the surface resitivity controlled by excess Na.
