Research progress on D-A-D type hole transporting materials for perovskite solar cells

摘要:

钙钛矿太阳能电池(Perovskite Solar Cells, PSCs)作为一种新型太阳能电池，由于其短时间内快速提升的光电转换效率而获得了全世界范围内的广泛关注。空穴传输材料(Hole Transporting Materials, HTM)是钙钛矿太阳能电池的重要组成部分，因此，设计开发经济、高效、稳定的HTM对PSCs的发展具有重要意义。本文综述了2009年以来线型给体-受体-给体(Donor-Acceptor-Donor, D-A-D)结构有机小分子空穴传输材料在PSCs中的应用，详细介绍了各空穴传输材料分子结构对PSCs的光电转换效率和器件稳定性等性能的影响。在此基础上，对未来线型D-A-D型空穴传输材料的发展进行了展望。

Abstract:

As a new type of solar cells, Perovskite solar cells (PSCs) have attracted worldwide attention due to their rapidly improved photoelectric conversion efficiency in a short time. Hole transporting materials (HTM) is an important part of perovskite solar cells. Design and synthesis of low-cost, efficient and stable HTM play a great role in the development of PSCs. This review summarizes the molecular engineering of organic small molecule HTM based on linear Donor-Acceptor-Donor (D-A-D) configuration and their application in PSCs since 2009. Meanwhile, we highlight the effect of molecular structure on the power conversion efficiency (PCE) and device stability of PSCs. Based on above result, the feature research interest on D-A-D type HTM are presented.
