  • Metal-based solution treatment of CIGS absorber layer in thin-film solar cells
    Patent number: 8748217
    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.
    Type: Grant
    Filed: November 13, 2012
    Date of Patent: June 10, 2014
    Assignee: TSMC Solar Ltd.
    Inventors: Chih-Ching Lin, Yong-Ping Chan, Kai-Yu Tung, Cheng-Tao Lee
