摘要

脂肪胺功能化苝-二亚胺（PDINN）具有强大的独特氢键和电子自掺杂效应，使有机太阳能电池（OSCs）效率的跨越式发展速度达到目前的最高水平。在这里，染料PDINN被二羧酸酯和四苯基磷酸基团修饰，得到两个阴极界面材料PDOEN和PDOP。PDOEN仍像PDINN一样保留半脂族胺官能团；PDOP具有四苯基溴化磷。这两种界面材料调整了表面润湿性、能级排列和物理接触性能，从而提高了器件性能。以PM6/Y6为光源体系，功率转换效率由PDINN基OSCs的15.43%提高到PDOEN基OSCs的15.88%。对于另一种光有源系统PM6/L8-BO，该参数也从17.13% （PDINN器件）提高到17.45% （PDOEN器件）。除了开路电压外，光电流的增加是值得注意的，可以通过光电流图技术直观地观察到。这两种pdi衍生物的性质表明，酯酰亚胺结构可作为开发高性能有机中间层材料的有效方案。

Interlayer enhancement of organic solar cells efficiency

aliphatic amine-functionalized perylene-diimide (PDINN) has strong unique hydrogen-bonding and electron self-doping effect so that it accelerates the leapfrog speed of organic solar cells (OSCs) efficiency to the highest present level. Here the dye, PDINN is modified by dicarboxylate and tetra-phenyl-phosphonium moieties obtaining two cathode interfacial materials PDOEN and PDOP. PDOEN is still retaining half aliphatic amine-function-group like PDINN; PDOP furnished with tetra-phenyl-phosphonium bromide. The two interfacial materials tuned the surface wettability, energy level alignment and physical contact properties, leading to device performance improvement. The power conversion efficiency was promoted from 15.43 % of PDINN based OSCs to 15.88 % of PDOEN based OSCs with PM6/Y6 as photo active system. For another photo active system PM6/L8-BO, this parameter also enhanced from 17.13 % (PDINN device) up to 17.45 % (PDOEN device). Except for the open circuit voltage, the photo current increasement is noteworthy and can be observed visually by photo-current map technology. The property of the two PDI-derivatives indicates that ester imide structures could be useful protocol in developing high-performance organic interlayer materials.

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.
