Abstract

The rational design of hole transport materials (HTMs) through precise molecular energy level modulation and enhanced interfacial coupling, offers a promising approach for improving perovskite solar cells (PSCs) performance. In this study, we designed and developed three novel acridine-derivative HTMs, termed as TAO, TAS, and TASO2, featuring tailored highest occupied molecular orbital (HOMO) energies and strengthened interfacial interactions with the perovskites layer. The TAS-based device obtained a champion power conversion efficiency (PCE) of 25.6% and demonstrated outstanding environmental stability. These results highlight the crucial role of optimized energy level alignment and interfacial passivation in designing efficient and stable HTMs for perovskite photovoltaics.

钙钛矿太阳能电池用具有可调桥接单元的二聚吖啶空穴传输材料

通过精确的分子能级调制和增强界面耦合来合理设计空穴传输材料（HTMs），为提高钙钛矿太阳能电池（PSCs）的性能提供了一条有前途的途径。在这项研究中，我们设计并开发了三种新的吖啶衍生物HTMs，分别称为TAO， TAS和TASO2，它们具有定制的最高已占据分子轨道（HOMO）能量，并加强了与钙钛矿层的界面相互作用。基于tas的器件获得了25.6%的冠军功率转换效率（PCE），并表现出出色的环境稳定性。这些结果强调了优化能级排列和界面钝化在设计高效稳定的钙钛矿光伏材料中的关键作用。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
