Over 12% Efficient CuIn(S,Se)2 Solar Cell with the Absorber Fabricated from Dimethylformamide Solution by Doctor‐Blading in Ambient Air

Abstract

Thin Film Solar Cells In article number 2200150, Weibo Yan, Hao Xin, and co-workers fabricated high quality CuInS2 precursor films from N,N-dimethylformamide molecular precursor solution by doctor-blading in ambient air. CuIn(S,Se)2 solar cells with a power conversion efficiency of 12.54% on a small area and 8.43% on 1 cm2 level have been achieved from doctor-bladed absorbers, demonstrating great potential of the solution approach for the low-cost industrial production of CuIn(S,Se)2 thin film solar cells.
