摘要

化学结构简单的共轭聚合物对于设计用于非富勒烯有机太阳能电池的高效宽带隙（WBG）给体材料具有吸引力。芴是有机光电材料中最常见的结构之一。在此，我们首次用肟基团官能化了的芴来构建具有 BDT 供体单元的 D-A 聚合物供体的受体单元。PBFO-H 和 PBFO-F 聚合物的 HOMO 值较低，具有 2.08 eV 的宽带隙，可溶于氯仿，易于加工。利用这些聚合物和非富勒烯 Y6 受体构建了有机太阳能电池。含氟聚合物（PBFO-F）的光电性能总体上优于非含氟聚合物，其 Jsc、Voc 和 FF 值分别为 23.17 mA/cm2、0.84 V 和 55.2 %，PCE 高达 10.71 %。这些结果表明，芴有望构建 D-A 宽带隙聚合物的受体单元。

Simple oxime functionalized fluorene polymers for organic solar cells

Conjugated polymers with simple chemical structure are attractive for the design of high efficiency wide bandgap (WBG) donor materials used in non-fullerene organic solar cells. Fluorene is one of the most common structures in organic opto-electronic materials. It is hereby used, for the first time, functionalized with oxime group to construct the acceptor unit of D-A polymer donors with a BDT donor unit. The polymers, PBFO-H and PBFO-F, had low-lying HOMO with a wide bandgap of 2.08 eV and are soluble in chloroform for easy processing. Organic solar cells were constructed using the polymers and non-fullerene Y6 acceptor. The fluorinated polymer (PBFO-F) had better photovoltaic properties over the non-fluorinated polymer in overall, with Jsc, Voc, FF values of 23.17 mA/cm², 0.84 V, and 55.2 % respectively, and a high PCE of 10.71 %. These results demonstrate that fluorene is promising in constructing acceptor units for D-A wide bandgap polymers.
