摘要: | We demonstrate regular-type perovskite solar cells based on vertically grown Ni-doped ZnO nanorod arrays and doped P3HT for solar energy harvesting. PCBM was introduced between Ni-doped ZnO nanorod arrays and the perovskite layer to improve electron extraction, while P3HT doped with bis(trifluoromethane) sulfonimide lithium salt (Li-TFSI) was used as hole transporting layer. Three types of perovskite materials, including MAPbI(3), (MA)(x)(FA)(1-x)PbI3, and (MA)(y')(GA)(1-y)PbI3, were used as light harvesting layers to exploit conversion efficiency of photovoltaic devices. The optimized perovskite solar cell with the configuration of ITO/Ni-doped ZnO nanorods/PCBM/(MA)(y)(GA)(1-y)PbI3/P3HT + Li-TFSI/Au revealed an open-circuit voltage of 0.83 V, a short-circuit current density of 23.73 mA/cm(2), a fill factor of 70%, and a power conversion efficiency of 13.79%.
