Abstract 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 photovoltaics (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 materials. It results in severe non-radiative recombination, limiting its further development and the commercialization. In this… More >
