A series of [60]fullerenes covalently functionalized with the polymer poly(ethylene glycol) is presented. These new [60]fullerene‐based materials have been incorporated as additives in CH₃NH₃PbI₃ (MAPbI₃), the most common organic–inorganic perovskite used in perovskite solar cells. The extensive photovoltaic study performed by using these materials shows several beneficial effects on the performance of these cells, including a reduction in hysteresis and an increased stability against moisture, whereby the solar cells retain up to 97 % of their initial power conversion efficiency in an ambient atmosphere.

钙钛矿型太阳能电池用聚乙二醇-[60]富勒烯基材料，具有改善的耐湿性和降低的滞后性

提出了一系列与聚合物聚乙二醇共价官能化的[60]富勒烯。这些新的[60]富勒烯类材料已被结合作为在CH添加剂₃ NH ₃碘化铅₃（MAPbI ₃），在钙钛矿的太阳能电池中使用的最常见的有机-无机钙钛矿。通过使用这些材料进行的广泛的光伏研究显示出对这些电池性能的几个有益影响，包括减少了磁滞现象和提高了对湿气的稳定性，从而使太阳能电池在环境中的初始功率转换效率高达97％。气氛。
