Renewable energy, such as solar energy, is infinite, readily available, and has extensive applications. Dye-sensitized solar cells (DSSCs) have been well developed; thus, they can be developed with low production costs, high efficiency, and facile manufacturing techniques. This study proposes a novel chitosan biopolymer-based perylene dye; the dye is modified by chitosan with perylene-3,4,9,10-tetracarboxylic anhydride using a one-pot acylation of nitrogen nucleophiles for DSSCs. The chitosan biopolymer-based perylene dyes were characterized using attenuated total reflection infrared spectroscopy, solid-state C CP-TOSS nuclear magnetic resonance spectroscopy, X-ray powder diffraction analysis, thermogravimetric analysis, X-ray photoelectron spectrometry, and high-resolution field-emission scanning electron microscopy. The ultraviolet-visible and fluorescence spectroscopy of chitosan biopolymer-based perylene dye exhibited a red-shift compared with perylene-3,4,9,10-tetracarboxylic anhydride and chitosan. The DSSC properties of chitosan biopolymer-based perylene dye were investigated, and it exhibited a 2.022 % power-conversion efficiency. Thus, this promising chitosan biopolymer-based perylene dye may have potential applications in solar-cell technology.
可再生能源，如太阳能，是无限的，随时可用的，并且有广泛的应用。染料敏化太阳能电池（DSSC）已经得到了很好的发展；因此，它们可以用低成本、高效率和简单的制造技术来开发。本研究提出了一种新型的壳聚糖基聚酰亚胺染料；该染料通过壳聚糖与均苯三甲酸酐的一锅氮亲核取代反应进行修饰，用于 DSSC。壳聚糖基聚酰亚胺染料的特性通过衰减全反射红外光谱、固态 C CP-TOSS 核磁共振光谱、X 射线粉末衍射分析、热重分析、X 射线光电子能谱和高分辨率场发射扫描电子显微镜进行了表征。壳聚糖基聚酰亚胺染料的紫外-可见和荧光光谱与均苯三甲酸酐和壳聚糖相比发生了红移。研究了壳聚糖基聚酰亚胺染料的 DSSC 性能，其表现出 2.022%的功率转换效率。因此，这种有前途的壳聚糖基聚酰亚胺染料可能在太阳能电池技术中有潜在的应用。
