| Popis: | Highly reproducible and photocurrent hysteresis-less inverted planar perovskite solar cells were demonstrated by a modified solvent annealing method in a two-step solution deposition (modified method). PbI2 film was annealing at 40 °C using the residue solvent after spin-coating, which facilitated the subsequent CH3NH3PbI3 perovskite active layer with high photovoltaic properties. The resulting device present a power conversion efficiency of 12.12%, which increased 42.7% compared with that of the control device fabricated as literatures. |
