摘要
Organic-inorganic hybrid perovskite solar cell(PSC)is a third-generation photovoltaic technology^([1,2]),and the certi-fied power conversion efficiency(PCE)has reached 25.5%(https://www.nrel.gov/pv/cell-efficiency.html),which can rival solar cells based on crystalline-Si and other inorganic semi-conductors.The intrinsic instability of perovskite materials could impede PSC commercialization^([3]).To date,a variety of strategies such as composition engineering,additive engi-neering,interface engineering and encapsulation technique are employed to improve the long-term stability of PSCs^([4−9]).
