Enhancing Photovoltaic Performance of Hybrid Perovskite Solar Cells Utilizing GaP Nanowires

GaP-based nanomaterials is a powerful tool for modern optoelectronic device fabrication owing to their excellent electrophysical properties, low optical losses, light localization, and optimal thermal conductivity. In our work, we incorporate GaP nanowires into perovskite solar cells to improve charge extraction from a perovskite layer without changing a total solar cell thickness. As a result, we improve the MAPbI3 perovskite solar cell efficiency up to 18.8% by VOC and JSC enhancement. The provided multiphysical theoretical simulations of the solar cells with the incorporated GaP nanowires describe the mechanism of charge extraction and optical absorption improvement. The developed method can be employed in various thin-film solar cells with different compositions of active material, as well as in other optoelectronic devices.
