A poly(3-hexylthiophene) (P3HT)-based inverted solar cell using indene-C60 bis-adduct (ICBA) as the acceptor achieved a high open-circuit voltage of 0.82 V due to ICBA's higher-lying lowest unoccupied molecular orbital level, leading to an exceptional power-conversion efficiency (PCE) of 4.8%. By incorporating a cross-linked fullerene interlayer, C-PCBSD, to further modulate the interface characteristics, the ICBA:P3HT-based inverted device exhibited an improved short-circuit current and fill factor, yielding a record high PCE of 6.2%.
基于聚 3-己基噻吩 (P3HT) 的倒置太阳能电池采用茚并[C60, C61]双加成物 (ICBA) 作为受体，由于 ICBA 较高的最低未占据分子轨道能级，实现了 0.82 V 的高开路电压，从而获得了卓越的功率转换效率 (PCE) 为 4.8%。通过引入交联富勒烯中间层 C-PCBSD 进一步调节界面特性，基于 ICBA：P3HT 的倒置器件表现出改善的短路电流和填充因子，产生了创纪录的 6.2%的高 PCE。
