Abstract Dye sensitized solar cells (DSSCs) were fabricated using extracted dyes from Hibiscus rosa-sinensis flower, helianthus annuus flower, mimosa pudica leaves, Luffa cylindrical flower and Lonchocarpus cyanescens leaves. The TiO2 photoelectrodes were prepared and deposited using Doctor blade method and then annealed at 450 °C. The elemental composition, structural and morphological studies of the TiO2 photoelectrodes were carried out as well. Optical properties of the dye extract and the dyed photoelectrodes was studied as well as their photoelectrochemical performances. The extracts showed the UV–Vis absorptions in the visible part of light spectrum. The DSSCs components were assembled into a cell module. The DSSC conversion efficiency was studied and DSSC based on dye extracts from Hibiscus rosa-sinensis flower, Helianthus annuus flower and Luffa cylindrical flower, Lonchocarpus cyanescens leaves and Mimosa pudica leaves revealed overall photocurrent conversion efficiencies of 0.48%, 0.35%, 0.29% 0.17% and 0.13% respectively.

使用来自选定植物的染料的染料敏化太阳能电池的比较光响应性能

摘要 采用从木槿花、向日葵花、含羞草叶、丝瓜圆柱花和蓝花香椿叶中提取的染料，制备了染料敏化太阳能电池（DSSCs）。使用刮刀法制备和沉积 TiO2 光电极，然后在 450°C 下退火。还进行了 TiO2 光电极的元素组成、结构和形态研究。研究了染料提取物和染色光电极的光学性质及其光电化学性能。提取物在光谱的可见光部分显示出紫外-可见吸收。DSSCs 组件被组装成一个电池模块。研究了 DSSC 转换效率，并基于芙蓉花染料提取物进行 DSSC，
