Description
Summary:This study investigated the effect of an inorganic interlayer (IL) of WS2 on the performance of perovskite solar cells (PSCs). The device configuration with IL consisted of Au/CuSbS2/CH3NH3SnI3/WS2/ZnO/Glass structure. The chemical instability of ZnO causes rapid perovskite breakdown upon its contact with metal halide perovskites. This can be addressed by inserting the IL between these two materials. The effect of different parameters including the thickness of WS2 and perovskite, the defect density of perovskite, and interfaces were investigated. Moreover, the impact of doping density of WS2 and the electron affinities of ZnO, CuSbS2, and WS2 were also studied. The results showed that the device performance with IL enhanced remarkably as PCE of 34.38%, JSC of 33.30 mA/cm2, VOC of 1.13 V, and FF of 91.16% compared to the device without IL. The research highlights the significant potential of interlayer-based PSCs and provides valuable insights for their further development.
