Two bodipy dyes with different carboxylic acids on the -position of the bodipy core were prepared and used to sensitize TiO photoelectrodes. On the basis of spectroscopic characterization, the photoelectrodes were used to fabricate photoelectrochemical cells (PECs) for solar light harvesting. Photovoltaic measurements showed that both bodipy dyes successfully sensitized PECs with short-circuit current densities () two-fold higher compared to the control. The increase in generated current was attributed to the gain in spectral absorbance due to the presence of bodipy. Finally, the influence of co-sensitization of bodipy and N719 dye was also investigated and photovoltaic device performance discussed.
制备了两种在硼二吡咯核心的β位带有不同羧酸的硼二吡咯染料，并用于敏化TiO光电极。基于光谱表征，这些光电极被用于制造用于太阳能光收集的光电化学电池（PEC）。光伏测量表明，与对照相比，两种硼二吡咯染料均成功地敏化了PEC，其短路电流密度（）高出两倍。产生电流的增加归因于由于硼二吡咯的存在而导致的光谱吸光度的增加。最后，还研究了硼二吡咯与N719染料共敏化的影响，并讨论了光伏器件的性能。
