Abstract

original image

Intelligent solution: A facile solution-based method is developed to fabricate high-efficiency CuIn(SeS)2 solar cells. Low-cost copper(I) oxide, indium hydroxide, carbon disulfide, and butylamine are used as the starting materials and used to make the precursor solution. A high conversion efficiency of up to 10.1 % for CuIn(SeS)2 solar cells is achieved without anti-reflection coating.
