Dendritic architectures with 1,2,3-triazole as the building unit and dimethyl isophthalate as the surface group are synthesized through a convergent approach employing click chemistry and tested for their application in dye-sensitized solar cells (DSSCs). The studies revealed that the presence of triazole and isophthalate groups in dendritic structures significantly altered the absorption, electrochemical and DSSC behaviors. In DSSCs, the dendritic structures exhibited higher Voc values and higher power conversion efficiency (η) in the I−/I3− redox couple under simulated conditions at 40 mW cm−2.
通过采用点击化学的聚拢方法,合成了以1,2,3-三氮唑为构建单元、以间苯二甲酸二甲酯为表面基团的树枝状结构,并对其在染料敏化太阳能电池(DSSCs)中的应用进行了测试。研究表明,三氮唑和间苯二甲酸基团存在于树枝状结构中,显著改变了吸收、电化学和DSSC行为。在DSSCs中,树枝状结构在40 mW cm−2的模拟条件下,在与I−/I3−氧化还原电对中表现出更高的Voc值和更高的功率转换效率(η)。
