近年来，基于“体异质结”的聚合物太阳能电池(PSCs)在薄膜中使用了简单的电子供体和受体材料的混合物得到了广泛的研究。虽然这种方法已经获得了相对较高的功率转换效率，但需要进一步改进以精确地构建稳定、可重复的纳米结构，这些结构既适合于有效的电荷分离，也适合于在此类薄膜中的传输。为此，非常需要利用自下而上的方法，例如无机和有机纳米结构的自组织形成。本文综述了近年来我们在PSCs纳米结构控制方面的研究进展。
Recently, polymer solar cells (PSCs) based on "bulk heterojunctions" using a simple mixture of electron donor and acceptor materials in thin films have been extensively studied. Although relatively high power conversion efficiencies have been achieved by using this approach, further improvement is necessary to precisely construct stable, reproducible nanostructures that are suitable for both efficient charge separation and transport inside such films. For this purpose, it is highly desirable to utilize a bottom-up approach, such as the self-organized formation of inorganic and organic nanostructures. In this review, an overview of our recent studies on the control of nanostructures in PSCs is presented.
