近年来,钙钛矿太阳能电池(PSCs)的效率得到了快速的发展,目前已经获得25.7%的认证效率,可与硅基太阳能电池相媲美。然而,PSCs的稳定性却远不如硅基太阳能电池,这限制了PSCs的使用。与此同时,二维(2D)或准二维钙钛矿材料受到了越来越多的关注,主要是因为大体积有机配体的引入明显地改善了材料的结构和环境稳定性。在2D PSCs领域,有机配体离子的设计和选择会直接影响材料的光电性能和器件的效率。目前,2D PSCs中所使用的有机配体主要分为脂肪族配体和芳香族配体。芳香族配体由于具有较大的介电常数、改善的电荷传输和可调控的组装结构等优点得到越来越多的关注。本文系统地总结了芳香族配体材料对2D钙钛矿性能的影响及其在2D PSCs领域的应用。
Perovskite solar cells(PSCs) have undergone unprecedented rapid development in the past decade. A certified power conversion efficiency (PCE) of 25.7% has been achieved, which is comparable to that of commercialized silicon solar cells. However, the inferior stability under heat and moisture has hindered their commercial application. Two-dimensional (2D) or quasi-2D perovskite materials have attracted considerable interest due to their superior structural and environmental stability in comparison with their 3D counterpart. The organic spacers play a very important role in 2D perovskites and they could directly affect the optoelectronic properties of the materials and the PCE of the devices. The organic spacers for 2D PSCs mainly include aliphatic spacers and aromatic spacers. The aromatic spacers have received more and more attention because of their large dielectric constants, superior charge transport properties and tunable self-assembly structures. In this review, we systematically summarize the effects of aromatic spacers on the structural and optoelectronic properties of 2D perovskite materials, and their applications in 2D PSCs.
