Applicability of alkoxysilyl group was examined for the first time as the anchor moiety of sensitizing dyes for dye-sensitized solar cells by using alkoxysilylazobenzenes. Alkoxysilylazobenzenes adsorbed efficiently onto TiO2 electrodes by the formation of Si–O–Ti bonds, and the electrodes exhibited much higher durability to water and better photovoltaic performance than in the case of a conventional carboxy dye.
通过使用烷氧基硅基偶氮苯,首次研究了烷氧基硅基作为染料敏化太阳能电池敏化染料的锚基的适用性。与传统的羧基染料相比,烷氧基硅基偶氮苯通过形成 Si-O-Ti 键有效地吸附在二氧化钛电极上,电极对水的耐久性更高,光电性能更好。
