In this study, high-quality CZTS nanocrystal films were prepared using a solvothermal method. The selection of sulfur source and surfactants were optimized, resulting in nanocrystal films with small particle size, high dispersion, and hydrophilic surfaces.
Due to the difficulties in achieving high purity, high dispersion, and uniform size distribution, solvothermal synthesis has been seldom employed to fabricate Cu2ZnSnS4 (CZTS) nanocrystals for photoelectrochemical ap-plications. Herein, a facile approach has been adopted for preparing CZTS nanocrystals using a solvothermal method. Employing various characterizations, and a thorough analysis of the photoelectrochemical performance, the impacts of different sulfur sources and surfactants on the products were investigated. High-quality CZTS nanocrystal films with small particle size, high dispersion, and hydrophilic surfaces were developed by utilizing proper solvents, cheap metallic ions, surfactants, and right sulfur source. The product that employed Na2S as its sulfur source had the highest phase purity and the closest stoichiometric ratio. The photoelectrochemical tests showed that CZTS nanocrystal films using polyvinylpyrrolidone as a surfactant had quicker light responsiveness and smaller dark current.
