Abstract
Constructing inorganic perovskite/organic-inorganic hybrid perovskite bilayer heterojunction perovskite solar cells (HPSC) could make far-reaching changes in solar cell power conversion efficiency (PCE). Herein, a carbon-based hole transport layer (HTL) free CsPbI3/MAPbI3 HPSC was designed and optimized by one-dimensional solar cell capacitance (SCAPS-1D) software. The film thickness, bulk defect density and doping concentration of each perovskite light absorption layer, and the interface defect density, the electrode work function and the operating temperature changes effect on the device performances were investigated. Under optimized conditions, the HPSC obtained the open circuit voltage (VOC) of 1.43 V, short circuit current density (JSC) of 23.39 mA cm−2, fill factor (FF) of 90.67 % and PCE of 30.33 %, which was much superior than the single junction perovskite solar cell due to the suited energy band structure.
