• spectroscopy, semitransparent Sb2S3 thin films can be rapidly grown in air by the area-scalable ultrasonic spray pyrolysis method. Integrated into a ITO/TiO2/Sb2S3/P3HT/Au solar cell, a power conversion efficiency (PCE) of 5.5% at air mass 1.5 global (AM1.5G) is achieved, which is a record among spray

• layers could be controlled by varying the spray deposition temperature and the molar ratio of precursors in spray solution. Nonuniform, discontinuous layers of polycrystalline Sb2S3 (Eg 1.8 eV) were deposited by ultrasonic spray pyrolysis of SbCl3/SC(NH2)2 1:3 solution at TD ≥ 220 °C or 1:6 solution at

High quality, uniform, pinhole-free coatings of polycrystalline orthorhombic Sb2S3 (Eg 1.8 eV, S/Sb 1.3) with lateral grain size as large as 10 μm were produced by crystallization of amorphous Sb2S3 layers in vacuum at

We demonstrated that Sb2S3 optical coatings with controllable structure, morphology and optical properties can be deposited by ultrasonic spray

As a spray technique, the goal is to produce one particle per droplet, but here the crystallization is controlled by
