| 摘 要： | 首先从高原金莲花中提取天然染料, 通过紫外-可见(UV-Vis)吸收光谱和傅里叶变换红外(FTIR)吸收光谱确定其主要成分为花色苷. 调节色素溶液的pH值, 组装染料敏化太阳能电池(DSCs)并进行光电性能测试.研究发现, 随着pH值的升高, 电池的开路电压逐渐升高, 但是短路电流密度却先升高后降低. 分析认为这是由于在不同pH值下, 花色苷的结构会发生转换造成的. 在pH=5时, 该天然染料敏化太阳能电池的光电转换效率最高, 达到0.292%.

| Abstract: | Trollius chinensis pigment was extracted, and ultraviolet-visible (UV-Vis) absorption and Fourier transform infrared (FTIR) spectroscopy confirmed that anthocyanin compounds were the main components. Dye sensitized solar cells (DSCs) were sensitized from the natural pigments dissolved in different pH solutions. Open-circuit voltage increased with increasing pH,while short-circuit current density first increased and then decreased, attributed to an anthocyanin structural change with pH value. The highest observed power conversion efficiency was 0.292% at pH=5. |
