The perovskite crystals formed by methylammonium lead iodide (MAPbI
3 ) have garnered growing interest owing to their exceptional photovoltaic capabilities, economical production process, and ability to be processed in solution. A multitude of techniques have been devised to produce dense and uniform perovskite thin coatings, which are critical for the proper functioning of electronic devices. In order to promote the development of CH3 NH3 PbI3 perovskite thin films that are uniform, dense, and exceptionally smooth, we present an additive-assisted method utilizing Copper zinc tin sulfide Cu2 ZnSnS4 (CZTS) nanoparticles. The surface, optical, morphological, and structural properties were subsequently determined. The mechanisms by which the additive improves the quality of the material during the formation of CH3 NH3 PbI3 perovskite films are elucidated in this study. These processes are postulated to characterize the crystallization of the films. Using this beneficial technique, a high-quality CH3 NH3 PbI3 film with a grain size significantly larger than 1.6 μm was effectively manufactured. Additionally, the doping process resulted in enhancements in both absorption and photoluminescence intensity. The addition of CZTS NPs elevated the crystal structures and morphologies of the CH3 NH3 PbI3 layer to a degree that was comparatively favorable. This was evidenced by the crystallite size of 83 nm and an optical bandgap (Eg) of 1.63 eV, both of which attest to the enhanced quality of the film. With the structure of glass/FTO/TiO2 /CH3 NH3 PbI3 :CZTS NPs/spiro-oMeTAD/Au ,the power conversion efficiency (PCE) of the best cell was 15.13% with a fill factor of 66.07%. The results of this study indicate that doping CH3 NH3 PbI3 solar cells with CZTS NPs is a dependable method for enhancing photovoltaic performance and promoting crystal growth.
