Organic bulk heterojunction photovoltaics, merely incorporating monoadducts of cyclopenteno[60]fullerenes (CPFs) as n‐type materials and P3HT as p‐type materials, display superior power conversion efficiency up to 4.6 ± 0.12%, superseding that with PC 61 BM/P3HT (3.8 ± 0.20%) for ca. 20%, under AM 1.5G irradiation―primarily attributed to the lack of homo‐conjugation on CPFs and their higher LUMO energy levels.
