제목 Enhanced performance of all inorganic strontium incorporated CsPbI2Br based perovskite solar cells in ambient condition
초록 In the present study, we fabricated an air processed strontium (Sr2+) partially replaced Pb in inorganic CsPbI2Br based inorganic perovskite solar cells in ambient condition. The morphology, crystallinity, absorption, elemental composition and photoluminescence of the air processed CsPb1-XSrXI2Br were studied systematically. The Sr providing a passivating effect on the surface of the perovskite. The perovskite solar cell using optimal concentration of Sr (x=0.02) doped CsPbI2Br achieved a 16.54 % power conversion efficiency, open circuit voltage (VOC) of 1.318 V, a short circuit current density (JSC) of 16.30 mAcm-2 and fill factor (FF) of 77 % which is much higher than controlled CsPbI2Br based inorganic PVSC. Our thermal analysis results showed an excellent thermal stability of 200 hours at 60 ᵒC thermal annealing. These results would provide a novel pathway to improve highly efficient and stable inorganic PVSCs.
