A series of metal-free benzotriazole-based dipolar dyes have been developed as sensitizers for dye-sensitized solar cells (DSSCs). Different heteroaromatic rings such as furan, thiophene, and selenophene, were used in combination with benzotriazole as the conjugated spacer group. Light harvesting, charge recombination, and electron injection of the cells fabricated are affected by the heteroaromatic ring used in the spacer. The DSSC with the thiophene-containing dye has the highest conversion efficiency of 6.20%, which reaches 85% of the standard cell based on N719.
一系列基于苯并三唑的无金属二极染料已被开发为染料敏化太阳能电池（DSSC）的敏化剂。不同的杂芳环，如呋喃、噻吩和硒吩，与苯并三唑一起用作共轭间隔基团。所制备的电池的光捕获、电荷复合和电子注入受到间隔基中使用的杂芳环的影响。含噻吩染料的 DSSC 的转换效率最高，为 6.20%，达到基于 N719 的标准电池的 85%。
