Solution-processed material systems for effective photovoltaic conversion are the key to low-cost and efficient solar cells. While antimony trisulfide (Sb2S3) is a promising absorber, solution-processed quality Sb2S3-based heterojunction cells, particularly with an open-circuit voltage (Voc) higher than 0.70 V, challenging issues.
