A new class of tribranched dye-sensitized solar cell (DSC) sensitizers carrying two conjugated donors and two acceptor/anchoring groups is introduced. The approach leads to significantly different optical properties and enhanced stability with respect to related di- and monobranched dyes and yields power conversion efficiencies of up to 5.05%, which is possibly limited by the computed nonoptimal dye
介绍了一类新的带有两个共轭供体和两个受体/锚定基团的三支化染料敏化太阳能电池 (DSC) 敏化剂。该方法导致显着不同的光学性质和相关的双支和单支染料的稳定性增强,并产生高达 5.05% 的功率转换效率,这可能受到半导体表面上计算的非最佳染料堆积的限制。
