Abstract


A perovskite solar cell with NiO and ZnO as charge transport layers was successfully fabricated. Intramolecular exchange technology was used to improve the morphology of CH3NH3PbI3 thin films. Doping was used to improve the conductivity of the NiO layer. X-ray diffractometer and scanning electron microscopy were used to analyze CH3NH3PbI3 thin films. A solar simulator with a digital source meter and quantum efficiency measurement system were used to test devices performance. The perovskite solar cells with FTO/p-NiO/CH3NH3PbI3/n-ZnO/Ag structure, have optimal PCE of 11.02% and long-term stability at 25 °C and 30 ± 2% humidity. This provides the possibility for the application of perovskite solar cells in the atmospheric environment
