Abstract The spray pyrolysis, as a non-vacuum cost-effective technique was used to develop high-quality thin films of SnO2 and Sb-doped SnO2 on Soda-lime glass substrates as transparent conductive oxides (TCOs). The surface morphology of the thin films under study was checked by the atomic force microscope. The average particle size and surface roughness of SnO2 and Sb-doped SnO2 thin films mainly depend on the Sb doping level. The structural identification of the as-deposited thin films has been investigated by the X-ray diffraction technique (XRD). XRD patterns have confirmed that the as-deposited thin films have a nanocrystalline structure with the tetragonal phase for all thin-film samples. The optical distribution of the transmittance and absorbance has been studied in a wide range of the wavelength (200–2500 nm). The absorption coefficient, optical band gap, and refractive index have been obtained by using the Swanepoel model. The optoelectronic properties for the thin films under study have been evaluated as TCOs films for photovoltaic applications. The sheet resistance and optical conductivity also have been determined for the thin film under investigation depending on the Sb doping level.

摘要 喷雾热解作为一种非真空成本效益高的技术，被用于在钠钙玻璃基板上开发高质量的 SnO2 和 Sb 掺杂 SnO2 薄膜作为透明导电氧化物 (TCO)。通过原子力显微镜检查所研究薄膜的表面形态。SnO2 和 Sb 掺杂的 SnO2 薄膜的平均粒径和表面粗糙度主要取决于 Sb 掺杂水平。已通过 X 射线衍射技术 (XRD) 研究了沉积薄膜的结构鉴定。XRD 图案已经证实，对于所有薄膜样品，沉积的薄膜都具有四方相的纳米晶体结构。透射率和吸光度的光学分布已经在很宽的波长范围内（200-2500 nm）进行了研究。吸收系数，光学带隙和折射率已通过使用 Swanepoel 模型获得。所研究薄膜的光电特性已被评估为用于光伏应用的 TCO 薄膜。还根据 Sb 掺杂水平确定了所研究薄膜的薄层电阻和光导率。
