Abstract

Recombination is the most critical process that controls the photovoltaic performance in dye-sensitized solar cells (DSCs). Herein, we successfully introduced a new triphenylamine-based starburst photosensitizer, RJ-C6 [3-(4-(bis(4-((2,4-bis(hexyloxy)phenyl)ethynyl)phenyl)amino)phenyl)-2-cyanoacrylic acid] grafted with extended alkyl groups and phenylethynyl bridges capable of arresting recombination more effectively and realizing enhanced light harvesting through improved conjugation and rigidity. Using a cocktail mixture of RJ-C6 with XY1b dye and asymmetric dual-species copper(II/I) electrolyte, we realized an efficiency of 10.40% under standard AM 1.5G, 100 mW cm−2 irradiation. Strikingly, the same co-sensitized devices exhibited panchromatic absorption overlapping the entire fluorescent light spectra, delivering efficiencies of 35% under 100 lux, 37% under 1000 lux and a record PCE of 40% under 4000 lux, taking DSCs one step closer to being used as an attractive candidate for indoor photovoltaic applications.

使用鸡尾酒星芒三苯胺染料和双种铜电解质的染料敏化太阳能电池的室内光电效率提高了 40
重组是控制染料敏化太阳能电池(DSC)光电性能的最关键过程。在此,我们成功地推出了一种新型三苯胺基星爆光敏剂 RJ-C6 [3-(4-(双(4-((2,4-双(己氧基)苯基)乙炔基)苯基)氨基)苯基)-2-氰基丙烯酸],该光敏剂接枝了扩展的烷基和苯乙炔桥,能够更有效地阻止重组,并通过改进的共轭和刚性实现更强的光收集。利用 RJ-C6 与 XY1b 染料的鸡尾酒混合物以及不对称双物种铜 (II/I) 电解质,我们在标准 AM 1.5G、100 mW/cm2 照射条件下实现了 10.40% 的效率。引人注目的是,同样的共敏化器件显示出与整个荧光灯光谱重叠的全色吸收,在 100 勒克斯下的效率为 35%,在 1000 勒克斯下的效率为 37%,在 4000 勒克斯荧光灯照明下的 PCE 达到创纪录的 40%,这使 DSC 离室内光伏应用的后继者更近了一步。
