Abstract: This review provides a systematic overview of the overall development of diverse perovskite solar cells. It encompasses major material systems including organic-inorganic hybrid perovskites, all-inorganic perovskites, lead-free perovskites, and metal-free perovskites, extending the discussion to low-dimensional and single-crystal perovskites. The article highlights that despite significant progress in laboratory efficiency, the commercial viability of perovskite solar cells continues to be hindered by fundamental challenges such as instability, lead toxicity, and difficulties in large-area fabrication. To address these issues, the field is focusing on strategies like composition engineering, dimensional control, interface modification, and defect passivation to enhance material properties and device stability. Future advancement hinges on balancing high efficiency with robust stability, developing environmentally benign materials, and facilitating the transition from laboratory research to industrial application.
