Research on bulk heterojunction organic solar cells has rapidly grown over the past two decades, and device performance has reached power conversion efficiencies over 13 %. In this focus review, we highlight design strategies used for the development of diketopyrrolopyrrole‐ and tetracyano‐based molecular donors. We also describe how tetracyano‐bridged non‐fullerene acceptors can be developed by a click‐type [2+2]‐cycloaddition–electrocyclic ring‐opening reaction of acetylene‐bridged small molecules with tetracyanoethylene by simple modification.

基于二酮吡咯并吡咯基和四聚体的桥连小分子,用于大体积异质结有机太阳能电池

在过去的二十年中,块状异质结有机太阳能电池的研究发展迅速,并且器件性能已达到超过13%的功率转换效率。在本重点综述中,我们重点介绍了用于开发基于二酮基吡咯并吡咯和四氰基的分子供体的设计策略。我们还描述了如何通过简单修饰通过乙炔桥联的小分子与四氰基乙烯的点击型[2 + 2]-环加成-电环开环反应来开发四氰基桥联的非富勒烯受体。
