Cover Feature: High Performance Inverted Planar MAPbI₃ Perovskite Solar Cells with a Simple Annealing Process (ChemNanoMat 6/2019)

MAPbI3 perovskite film has been prepared by a simple and fast annealing method. The annealing process includes suspending annealing and a contact annealing step. The MAPbI3 perovskite film exhibits improved crystallization after being annealed at 90 °C. An ITO/PEDOT:PSS/perovskite/PCBM/Bphen/Ag solar cell was also fabricated, and both MAPbI3 perovskite solar cell electrode deposition and photoelectric performance tests were performed in ambient air, which could help reduce the production cost. The solar cell showed a PCE of 17.12 % and could work stably for a long time.
