The incorporation of small amounts of phenolic antioxidants, such as 2,6-di-tert-butyl-4-cresol and pentaerythritol tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], into photovoltaic organo-lead halide perovskite layers significantly suppressed the degradation of the perovskite compounds via light irradiation in the presence of ambient oxygen. While the facile incorporation of the antioxidants did not decrease both the quality of the formed perovskite crystal grains and the photovoltaic conversion performance of the cells, it enhanced the antioxidizing property and water repellency of the perovskite layer owing to the elimination of superoxide anion radical and hydrophobic molecular structure and improved the durability of the cells.

将少量酚类抗氧化剂，例如2,6-二叔丁基-4-甲酚和季戊四醇四[3-（3,5-二叔丁基-4-羟苯基）丙酸酯]掺入有机铅卤化物钙钛矿层在环境氧存在下通过光照射显着抑制钙钛矿化合物的降解。尽管简便地掺入抗氧化剂并不会降低钙钛矿晶粒的形成质量和电池的光电转换性能，但由于消除了超氧阴离子自由基和疏水性，它增强了钙钛矿层的抗氧化性和疏水性分子结构，提高了细胞的耐久性。
