Abstract

The invention relates to a rapid preparation method of an antimony sulfide thin film, which comprises the following steps: in a vacuum chamber, placing a substrate on a substrate frame with good surface layer heat-conducting property, enabling the metal surface of the substrate to face downwards, placing a substrate on which antimony sulfide powder is uniformly distributed, namely an evaporation source, on the lower side of the substrate frame, and enabling the distance between the substrate and the evaporation source to be 10-20mm; and evaporating and depositing antimony sulfide powder through temperature control, enabling an antimony sulfide thin film to directly grow on the metal surface of the substrate, wherein the growth speed of the antimony sulfide thin film is larger than 1.2 micrometers / min. The method is beneficial to quickly and efficiently preparing the high-quality antimony sulfide film.

Description

technical field [0001] The invention belongs to the field of photoelectric and energy storage material preparation, and in particular relates to a rapid preparation method of an antimony sulfide thin film. Background technique [0002] Antimony sulfide (Sb 2 S 3 ) is an emerging material with low cost and rich reserves of constituent elements. It has stable chemical properties, moderate band gap, and good light absorption performance. It has great development potential as a photoelectric and energy storage material, and has been extensively studied at present. [0003] In recent years, antimony sulfide thin-film solar cells have developed rapidly, and the general photoelectric conversion efficiency of corresponding devices can reach more than 6%, but its highest efficiency has never exceeded 8% since it reached 7.5% in 2014. In most of the currently known antimony sulfide thin film batteries, antimony sulfide is deposited on the metal oxide or other metal compound buffer l...
