| 摘 要： | 从高原黑枸杞中提取染料, 利用紫外-可见吸收光谱和循环伏安方法研究不同pH染料的光电化学性能, 确定染料最佳pH。以石墨烯为原料制备不同含量乙基纤维素(EC)的石墨烯纳米片(GNs)对电极, 用电化学阻抗、循环伏安、塔菲尔极化曲线研究不同EC含量对GNs对电极电催化性能的影响。以最佳pH染料为光敏剂, 不同含量EC的GNs为对电极组装染料敏化太阳能电池在模拟太阳光下测试光电转换效率。结果表明, EC含量为10wt%时, GNs对电极有良好的电催化性。光电测试EC含量为10wt%的GNs对电极光电转换效率为0.92%, 接近Pt对电极(0.99%)。

| Abstract: | The natural dye was extracted from Lycium ruthenicum Murray which was cultivated in Tibetan Plateau. The UV-Vis absorption spectra and cyclic voltammetry were used to characterize the dyes and confirm the optimal pH of the dye solutions. The influence of different contents of ethyl cellulose(EC) on the performance of electric catalytic of graphene nanoplates(GNs) counter electrode were investigated through electrochemical impedance spectra, cyclic voltammetry and Tafel polarization curve. DSCs were assembled by using the natural pigments with optimal pH as sensitizers and the GNs counter electrode with different contents of EC as counter electrode. It was found that the GNs counter electrode with 10wt% EC achieved the best performance of electric catalytic. The highest power conversion efficiency of the GNs counter electrode with 10wt% EC was 0.92%, close to that of Pt counter electrode (0.99%). |
