Organic-inorganic hybrid perovskites exhibit excellent optoelectronic properties, such as high absorption coefficients, long carrier diffusion lengths and lifetimes, low-temperature solution processibility and so on. The highest recorded power conversion efficiency (PCE) of perovskite solar cells (PSCs) has reached 25.5%, displaying huge potential for their commercialization. Here, the definition and classification of perovskite semiconductors are first summarized. Subsequently, strategies to enhance the PCE and stability, development of lead-free perovskite alternatives and recent advances in the fabrication of large area devices are highlighted. Last but not the least, the economic feasibility of PSCs and the future prospects for commercialization are also discussed, which could be used as a reference for the future study and development of PSCs.
