Carrier dynamics in organic solar cells materials with non-fullerene acceptors

近年来,非富勒烯有机小分子受体的出现推动了有机太阳能电池领域的蓬勃发展.然而,非富勒烯有机小分子受体的光物理机制以及基于它们的有机太阳能电池的光电转换机制仍不清楚,严重制约了高性能有机太阳能电池的高效开发.本文简要介绍了本课题组近年来在有机太阳能电池受体材料载流子动力学方面的研究进展.尝试通过研究端基工程、侧链工程和骨架工程对小分子受体载流子动力学的影响,建立结构-动力学-器件性能关系,推动有机太阳能电池的进一步发展.

The emergence of non-fullerene organic small molecule acceptors in recent years has promoted vigorous developments of organic solar cells.However,photophysical mechanism of non-fullerene organic small molecule acceptors and photoelectric conversion mechanism are unclear,seriously hampering efficient development of high-performance organic solar cells.Progress of our studies of carrier dynamics in acceptor materials of organic solar cells are introduced.Effects of terminal group engineering,side chain engineering and skeleton engineering on carrier dynamics of small molecule acceptors are studied.A structure-dynamics-device performance relationship is built to promote further development of organic solar cells.
