N2 - Due to the long carrier lifetime, high carrier mobility, and high absorption coefficient of perovskite materials, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has increased from 3.8% in 2009 to 25.7% in 2021, which have already surpassed the PCE of thin-film solar cells and closes to the efficiency of Si-based photovol-taics (26.7%). Therefore, PSCs have become a promising clean energy technology for commercialization. However, the low defect formation energy of perovskite leads to a higher defect density than other conventional photovoltaic mate-rials. It results in severe non-radiative recombination, limiting its further development and the commercialization. In this review, we summarize the mechanism and strategies for high-quality perovskite absorber fabrications to minimize the bulk and surface/interface defects of halide perovskite, including film quality development and interface modifica-tion. Strategies are proposed for further promoting the film quality and the corresponding device performance. Finally, we highlight the challenges that need to be overcome to control over the defect properties of halide perovskite.
