Earth abundant CuSbS2 thin films solution processed from thiol–amine mixtures

Abstract

Solution processing is a practical low-cost strategy for depositing semiconductor thin films. A binary thiol–amine solvent mixture dissolves bulk Cu₂S and Sb₂S₃ under ambient conditions, allowing for solution deposition and low temperature recovery of CuSbS₂. The resulting films of earth abundant CuSbS₂ possess optoelectronic properties suitable for photovoltaic applications.
