Interfacial Modification by Porphyrin/Phthalocyanine Complexes for Perovskite Solar Cells

为解决资源短缺和环境污染问题,太阳能电池应用研究引起了广泛的科学关注。在过去的十年间,钙钛矿太阳能电池(PSCs)作为一种新型的电池技术得到了快速发展,逐渐成为目前商业化硅基太阳能电池最有力的竞争对手之一。然而,钙钛矿薄膜在低温溶液制备过程中会不可避免地形成缺陷,这些缺陷是严重制约PSCs光电转化效率与长期运行稳定性得到进一步提高的主要因素。利用功能化有机分子钝化钙钛矿薄膜表面及晶界处缺陷是提升电池性能及稳定性的有效手段。卟啉/酞菁金属配合物具有良好的稳定性和优异的光电特性,利用卟啉/酞菁金属配合物修饰钙钛矿薄膜是提高PSCs性能和稳定性的有效方法之一。本文综述了卟啉/酞菁金属配合物界面调控实现高效稳定PSCs组装的研究进展,并对其存在的问题及今后可能的发展方向进行了总结与展望。

In order to solve the problems of energy shortage and environmental pollution,the research of solar cells has attracted extensive scientific attention.Over the past decade,perovskite solar cells(PSCs)have been developing rapidly,gradually becoming one of the most powerful competitors for commercial silicon-based solar cells.However,the inevitable formation of inherent crystallographic defects during the low-temperature solution process severely limits the improvement of the efficiency and stability of PSCs.Porphyrin/phthalocyanine metal complexes with the excellent stability and photovoltaic properties have been considered for improving the efficiency and long-term stability of cells by using porphyrin/phthalocyanine complexes to passivate defects on the surface and grain boundaries of perovskite films.In this review,we summarize the research progress of highly efficient and stable perovskite solar cells using porphyrin/phthalocyanine metal complexes to modify the perovskite films.Meanwhile,the existent problem and future development of PSCs with porphyrin/phthalocyanine complexes are discussed as well.
