摘要

采用吩噻嗪和两个吸电子基团设计合成了4种有机增敏剂。为了评估其对颜色和光伏性能的影响，我们用硫代靛蓝代替了吩噻嗪的碱性氢。测定了染料在两种极性溶剂（乙腈和乙醇）和一种非极性溶剂（苯）中的吸附性能，结果表明，在极性溶剂中吸附效果最好。并对其发射特性和光电极性能（二氧化钛对染料敏化）进行了评价。结果表明，由于j聚集，染料在乙醇和半导体上的吸收最大值发生了色移。最后，分别采用单独敏化和共敏化两种方法制备DSSCs，其中染料4单独敏化的效率最高，约为7.82 %，染料2+染料4共敏化的效率约为8.06 %。

Study of the presence of thioindigo in photosensitizers based on phenothiazine: Synthesis and photovoltaic evaluation in DSSCs

Four organic sensitizers were designed and synthesized using phenothiazine and two electron-withdrawing groups. To evaluate its effect on color and photovoltaic properties, we replaced the basic hydrogen of phenothiazine with thioindigo for this purpose. The absorption properties of the dyes were evaluated in two polar solvents (acetonitrile and ethanol) and a non-polar solvent (benzene), which showed that the maximum absorption was obtained in polar solvents. The emission and photoelectrode properties (titanium dioxide sensitized to dyes) were evaluated. The results showed that a bathochromic shift was observed in the absorption maximum of the dyes in ethanol and on the semiconductor due to the J-aggregation. Finally, DSSCs were prepared by two individual and co-sensitization approaches, with the highest efficiency in the individual method corresponding to Dye 4, about 7.82 %, and in the co-sensitization arrangement for Dye 2+Dye 4, about 8.06 %.
