Uniform Sb2S3optical coatings by chemical spray method

Abstract: 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). 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 depos… Show more

“…The substrate coverage of Sb 2 S 3 layers on a glass/ITO/TiO 2 substrate, annealed in vacuum, depends on the quantity of Sb 2 S 3 deposited by USP [46]. Thinner (≤70 nm) Sb 2 S 3 layers contain pin-holes (Fig.…”

“…1), which are characteristic of amorphous Sb 2 S 3 [28,46]. After vacuum annealing, characteristic narrower bands of Sb 2 S 3 are detected, which is an expected result when crystalline Sb 2 S 3 is formed [28,46,49]. No traces of additional phases were detected by either XRD or Raman in any glass/ITO/TiO 2 /Sb 2 S 3 samples.…”
