摘　　要：采用太阳电池模拟软件SCAPS-1D,对以CuGaO2为空穴传输层的钙钛矿太阳电池进行数值模拟,设计电池器件结构为FTO/TiO2/CH3NH3Pbl3/CuGaO2/Au,讨论了吸收层厚度及缺陷态密度、电子传输层厚度、电子亲和势、金属背电极功函数对电池性能的影响。通过模拟优化,电池性能得到一定提高,优化后的/-V特性为:V(OC)=1.20V,J(SC)=24.36mA/cm^2,FF=87.31%,η(PCE)=25.61%,为新型、高效钙钛矿太阳电池的结构设计以及工艺制备提供一定的指导思路。Perovskite solar cell based on CuGaO2 as hole transporting layer was simulated by solar cell simulation software SCAPS-1 D.The device structure was designed as FTO/TiO2/CH3 NH3 Pbl3/CuGaO2/Au;the thickness and the defect density of absorption layer,the thickness of electron transporting layer,the electron affinity and the work function of metal back electrode were discussed.The performance of solar cell was enhanced after simulation and optimization,and the better performances were VOC=1.20 V,JSC=24.36 mA/cm2,FF 87.31%,ηPCE=25.61%.It has instructive significance to the structure design and preparation process of high-performance and new-type perovskite solar cell.
