Antimony sulfide (Sb2S3) is a promising photon‐harvesting material for solar cells. Herein, a facile one‐step deposition method is reported for controllably preparing Sb2S3nanoparticle films with a preferential [221]‐orientation to a certain extent from a novel precursor solution, formed by dissolving antimony acetate and thiourea in acidifiedN,N‐dimethylformamide. With titania (TiO2) nanoparticle films as substrates for in situ‐growing Sb2S3films, the high‐quality Sb2S3/TiO2planar heterojunction films are obtained for efficient solar cells. The effects of the concentration and [S]/[Sb] molar ratio in the precursor solution on the Sb2S3film formation and the device performance are investigated. A considerable power conversion efficiency of 5.74% is achieved under AM 1.5G illumination (100 mW cm−2), which is the highest efficiency for the solar cells based on solution‐processed Sb2S3nanoparticle films by one‐step deposition method without further modification. A promising solution‐processing method is provided to prepare high‐quality Sb2S3films for efficient solar cells and other optoelectronics.
