Overcoming Intrinsic and Extrinsic Challenges in Perovskite Solar Cells: A Pathway Toward Advancement

This study underscores the urgency of tapping into Earth’s solar abundance for electricity through renewable sources. As global solar PV capacity rises, the focus sharpens on boosting solar cell efficiency and cutting manufacturing costs. Third-generation Perovskite Solar Cells (PSCs) show promise to dominate with an anticipated 25.8% power conversion efficiency (PCE) in under a decade. Despite record efficiencies, the long-term stability of lead halide perovskites faces challenges from fragile bonds and mobile ions. Advanced techniques reveal insights into moisture, heat, and light-induced alterations on perovskite lattices. Efforts to systematically address degradation pathways are underway, with the potential for commercially competitive photovoltaic technology as multiple PSCs demonstrate strong performance and extended lifetimes.
