摘　　要：目的:鉴于蓝莓花青素作为敏化剂在天然染料敏化太阳能电池(DSSC)中展现出的稳定性不足问题,系统优化反应参数及其性能提升机制。方法:采取丁二酸对蓝莓染料酰化修饰,并对酰化产物进行光电性能测试。结果:在蓝莓质量与无水乙醇体积比为1 g/15 mL、反应温度为40℃、反应时间为4 h条件下,酰化蓝莓花青素呈现最佳紫外-可见光(UV-Vis)光谱特性。酰化花青素染料的吸光强度比未酰化染料提升1.8倍,其中光稳定性和热稳定性均有所提高。太阳光模拟器测试表明,酰化后蓝莓花青素染料作为敏化剂组装的DSSC光电转换效率比未酰化花青素染料组装的DSSC光电转换效率提升46%。结论:本研究为天然染料分子工程提供一种化学修饰路径,为开发低成本、高稳定性天然染料敏化太阳能电池提供参考。Objective:In view of the insufficient stability of blueberry anthocyanins as sensitizers in natural dye-sensitized solar cells(DSSC),the reaction parameters and their performance improvement mechanisms were systematically optimized.Methods:The acylation of blueberry dye was modified by succinic acid,and the photoelectric properties of the acylation products were tested.Results:Acylated blueberry anthocyanins showed the best UV-Vis spectral characteristics by adjusting the volume ratio of blueberry mass to absolute ethanol to 1 g/15 mL,the reaction temperature at 40℃,and the reaction time at 4 h.The absorbance of acylated anthocyanin dyes was 1.8 times higher than that of unacylated dyes,and the photostability and thermal stability were improved.The solar simulator test shows that the photoelectric conversion efficiency of DSSCs assembled with acylated blueberry anthocyanin dye as sensitizer is 46%higher than that of DSSC assembled without acylated anthocyanin dye.Conclusion:This study provides a chemical modification path for the molecular engineering of natural dyes,and provides a reference for the development of low-cost and high-stability natural dye-sensitized solar cells.
