一系列不含金属的苯并三氮唑偶极染料已被开发为染料敏化太阳能电池的增感剂。不同的杂芳环，如呋喃、噻吩环和硒环，与苯并三唑作为共轭间隔基组合使用。电池的光捕获、电荷复合和电子注入受到间隔物中使用的杂芳环的影响。以N719为基础的标准电池的转换效率最高，为6.20%，达到标准电池的85%。
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.
