 Abstract perovskite solar cells, PSCs, have gained global attention due to their high efficiency and low manufacturing cost, with steady improvements in both efficiency and stability. Research continues to reduce lead leakage and develop eco-friendly lead-free perovskites, pushing forward the commercialization of PSCs. This review summarizes recent progress in PSCs, including efficiency, stability, tandem devices, and lead-free PSCs, as well as challenges toward practical application in module development.
