biostudies-literatureUnknown10Eensalu JSAntimony sulfide (Sb₂S₃), an environmentally benign material, has been prepared by various deposition methods for use as a solar absorber due to its direct band gap of ≈1.7 eV and high absorption coefficient in the visible light spectrum (1.8 × 10⁵ cm^-1 at 450 nm). Rapid, scalable, economically viable and controllable in-air growth of continuous, uniform, polycrystalline Sb₂S₃ absorber layers has not yet been accomplished. This could be achieved with chemical spray pyrolysis, a robust chemical method for deposition of thin films. We applied a two-stage process to produce continuous Sb₂S₃ optical coatings with uniform thickness. First, amorphous Sb₂S₃ layers, likely forming by 3D VoBeilstein journal of nanotechnology198-210https://www.ebi.ac.uk/biostudies/studies/S-EPMC6350889biostudies-literatureUniform Sb₂S₃ optical coatings by chemical spray method.PMC6350889Krunks MEensalu JSMere AKaterski AKarber EOja Acik IfalseUniform Sb₂S₃ optical coatings by chemical spray method.Antimony sulfide (Sb₂S₃), an environmentally benign material, has been prepared by various deposition methods for use as a solar absorber due to its direct band gap of ≈1.7 eV and high absorption coefficient in the visible light spectrum (1.8 × 10⁵ cm^-1 at 450 nm).
