Organic solar cells have made rapid progress in the last two decades due to the innovation of conjugated materials and photovoltaic devices. Microphase separation that connects with materials and devices plays a crucial role in the charge generation process. In this account, we summary our recent works of developing new crystalline conjugated polymers to control the microphase separation in thin films in order to realize high performance in solar cells, including crystalline diketopyrrolopyrrole-based donor polymers, perylene bisimide-based electron acceptors, and "double-cable" conjugated polymers that contain covalently-linked crystalline donor and acceptor in one material for single-component organic solar cells.
在过去二十年中，由于共轭材料和光电器件的创新，有机太阳能电池取得了快速进展。与材料和器件相关的微相分离在电荷产生过程中起着至关重要的作用。在本综述中，我们总结了我们最近开发新型结晶共轭聚合物以控制薄膜中的微相分离从而在太阳能电池中实现高性能的工作，包括基于结晶二酮吡咯并吡咯的供体聚合物、基于苝二酰亚胺的电子受体，以及在一种材料中包含共价连接的结晶供体和受体的用于单组分有机太阳能电池的“双电缆”共轭聚合物。
