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

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.
