Uniform Sb<sub>2</sub>S<sub>3</sub>optical coatings by chemical spray method
Abstract
<jats:p>Antimony sulfide (Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub>), 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 × 10<jats:sup>5</jats:sup>cm<jats:sup>−1</jats:sup>at 450 nm). Rapid, scalable, economically viable and controllable in-air growth of continuous, uniform, polycrystalline Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub>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 Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub>optical coatings with uniform thickness. First, amorphous Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub>layers, likely forming by 3D Volmer–Weber island growth through a molten phase reaction between SbCl<jats:sub>3</jats:sub>and SC(NH<jats:sub>2</jats:sub>)<jats:sub>2</jats:sub>, were deposited in air on a glass/ITO/TiO<jats:sub>2</jats:sub>substrate by ultrasonic spraying of methanolic Sb/S 1:3 molar ratio solution at 200–210 °C. Second, we produced polycrystalline uniform films of Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub>(<jats:italic>E</jats:italic><jats:sub>g</jats:sub>1.8 eV) with a post-deposition thermal treatment of amorphous Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub>layers in vacuum at 170 °C, <4 × 10<jats:sup>−6</jats:sup>Torr for 5 minutes. The effects of the deposition temperature, the precursor molar ratio and the thermal treatment temperature on the Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub>layers were investigated using Raman spectroscopy, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy and UV–vis–NIR spectroscopy. We demonstrated that Sb<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub>optical coatings with controllable structure, morphology and optical properties can be deposited by ultrasonic spray pyrolysis in air by tuning of the deposition temperature, the Sb/S precursor molar ratio in the spray solution, and the post-deposition treatment temperature.</jats:p>
