Abstract
A method for manufacturing a thin film solar cell device includes forming a back contact layer on a substrate, forming an CIGS absorber layer on the back contact layer, treating the CIGS absorber layer with a metal-based alkaline solution, and forming a buffer layer on the CIGS absorber layer where the treatment of the CIGS absorber layer improves the adhesion between the CIGS absorber layer and the buffer layer and also improves the quality of the p-n junction at the CIGS absorber layer/buffer layer interface.
