Applications Of Graphene in Perovskite Solar Cells

Abstract

Solar energy is a clean energy source with abundant reserves. Solar cells, which can convert solar energy into electricity, have become a research hotspot. Perovskite solar cell is a type of solar cell that is environmental-friendly and high security. It exhibits high theoretical output potential. People pay much attention to improve the efficiency of perovskite solar cells. As a result, it has garnered significant attention and investment in recent years. Doping nanomaterials with excellent performance are an effective means for modifying perovskite solar cells. Graphene, as a nanomaterial, can enhance the stability and photovoltaic efficiency of perovskite solar cell systems. Therefore, using graphene to modify perovskite solar cells has become a current research hotspot. In this work, the structure, properties, and application of graphene materials in perovskite solar cells are discussed. Perovskite solar cells modified by passivating perovskite solar cells with graphene is highlighted. In addition, graphene oxide combined with TiO₂ is discussed as a way to improve the performance of solar cells. This work helps to inspire new ideas for the modification of perovskite solar cells.
