The performance of organic photovoltaic devices based upon bulk heterojunction blends of donor and acceptor materials has been shown to be highly dependent on the thin film microstructure. In this tutorial review, we discuss the factors responsible for influencing blend microstructure and how these affect device performance. In particular we discuss how various molecular design approaches can affect the thin film morphology of both the donor and acceptor components, as well as their blend microstructure. We further examine the influence of polymer molecular weight and blend composition upon device performance, and discuss how a variety of processing techniques can be used to control the blend microstructure, leading to improvements in solar cell efficiencies.
基于给体和受体材料的体异质结混合物的有机光伏器件的性能已被证明高度依赖于薄膜微结构。在本教程综述中，我们讨论了影响共混物微结构的因素，以及这些因素如何影响器件性能。特别是，我们讨论了各种分子设计方法如何影响给体和受体组分的薄膜形态及其共混物微结构。我们进一步研究了聚合物分子量和共混物组成对器件性能的影响，并讨论了各种处理技术如何用于控制共混物微结构，从而提高太阳能电池的效率。
