Hybrid Perovskite/GaP nanowires solar cells with enhanced photovoltaic performance

In this work we report an improved photovoltaic performance of hybrid halide perovskite solar cell with integrated into a active layer GaP nanowires. The incorporation of GaP nanowires improves charge extraction from a perovskite layer. As a consequence, we boost the MAPbI3 perovskite solar cell efficiency up to 18.8% by open-circuit voltage and short-circuit current density enhancement. The provided multi-physical theoretical simulations of the solar cells with the incorporated GaP nanowires describe the mechanism of charge extraction and optical absorption improvement.
