Near-IR absorbing zinc fluorenocyanine complexes 1-3 were designed and synthesized as a cosensitizer for bulk-heterojunction solar cells. Fusing fluorene rings with the porphyrazine rings resulted in narrower band gap and stabilization of both the HOMO and LUMO energy levels compared with a zinc phthalocyanine complex. The synthesized fluorenocyanines 1-3 were incorporated into bulk-heterojunction solar cells based on regioregular poly(3-hexylthiophene) and 1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C61. The addition of 3 decorated with eight alkyl chains resulted in improved device performance with a 16% enhancement of the short circuit current compared with that of the reference cell without 3.
近红外吸收锌芴氰基配合物 1-3 被设计并合成作为体异质结太阳能电池的共敏化剂。将芴环与卟啉环融合，与锌酞菁配合物相比，导致带隙变窄，并且 HOMO 和 LUMO 能级更加稳定。合成的芴氰基 1-3 被掺入基于规正聚（3-己基噻吩）和 1-（3-甲氧基羰基）-丙基-1-苯基-（6,6）C61 的体异质结太阳能电池中。添加用八个烷基链修饰的 3 导致器件性能得到改善，与没有 3 的参考电池相比，短路电流增加了 16%。
