Abstract

Combination of organic donor–linker–acceptor dyes for panchromatic enhancement in photoelectrodes of dye-sensitized solar cells enables their environmentally friendly and cost-effective design. A promising combination in terms of spectral broadening and miscibility are the dyenamo red and blue dyes, which differ only in their molecular structure via linkers. In this work, we investigate the sequential co-sensitization of both dyes together with the co-adsorption of aggregation inhibitor, chenodeoxycholic acid to increase the optical absorption and energy conversion efficiency. Finally, with a J_SC of 10.2 mA cm⁻² and a V_OC of 584 mV, a small increase was achieved.

Graphical abstract

Combining Dyenamo Red and Blue dyes with chenodeoxycholic acid in dye-sensitized solar cells enhances optical absorption and energy efficiency. These combination enable cost-effective, environmentally friendly designs by broadening the spectral range and improving miscibility through sequential co-sensitization and co-adsorption techniques.

染料敏化太阳能电池的红蓝共敏化：顺序方法

有机给体-连接体-受体染料组合用于染料敏化太阳能电池光电极的全色增强，使其具有环保和成本效益的设计。在光谱展宽和混溶性方面，一个很有前途的组合是染料红和蓝色染料，它们的区别只是通过连接剂的分子结构。在这项工作中，我们研究了两种染料的顺序共敏以及聚集抑制剂鹅去氧胆酸的共吸附，以提高光吸收和能量转换效率。最后，JSC为10.2 mA cm−2，VOC为584 mV，实现了小幅提高。在染料敏化太阳能电池中，将Dyenamo红色和蓝色染料与chenodeoxycholic酸结合，提高了光吸收和能量效率。这些组合通过扩大光谱范围和通过顺序共敏和共吸附技术改善混溶性，使设计具有成本效益和环境友好性。

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
