综述了有机光伏(OPV)分子施主材料化学的一些最新进展。虽然分子材料从一开始就被用来制造OPV细胞，但专门为OPV设计的分子供体的设计是一个相对较新的研究领域。在过去的几年里，分子供体已经被用于真空沉积和溶液处理的OPV电池，这两个领域都取得了令人印象深刻的进展，功率转换效率超过了10%的象征性限制。然而，这一进步是以活性材料的化学和器件制造技术的日益复杂为代价的。这一演变可能是研究进展所固有的，但很难与OPV显示出相对于现有硅技术的决定性经济优势的必要性相一致。在这篇简短的综述中，讨论了各种类型的分子给体，目的是定义可能的基本分子结构，这些结构可以结合结构简单、低相对分子质量、合成可获得性和可扩展性，并且可以代表开发简单和经济高效的OPV材料的可能起点。
An overview of some recent developments of the chemistry of molecular donor materials for organic photovoltaics (OPV) is presented. Although molecular materials have been used for the fabrication of OPV cells from the very beginning of the field, the design of molecular donors specifically designed for OPV is a relatively recent research area. In the past few years, molecular donors have been used in both vacuum-deposited and solution-processed OPV cells and both fields have witnessed impressive progress with power conversion efficiencies crossing the symbolic limit of 10%. However, this progress has been achieved at the price of an increasing complexity of the chemistry of active materials and of the technology of device fabrication. This evolution probably inherent to the progress of research is difficult to reconcile with the necessity for OPV to demonstrate a decisive economic advantage over existing silicon technology. In this short review various classes of molecular donors are discussed with the aim of defining possible basic molecular structures that can combine structural simplicity, low molecular weight, synthetic accessibility, scalability and that can represent possible starting points for the development of simple and cost-effective OPV materials.
