The sensitization activity of four zinc metalloporphyrin dyes: meso-tetrakis(4-pyridyl)porphyrinato Zn(II) (a), meso-triphenyl-(4-carboxyphenyl)porphyrinato Zn(II) (b), meso-tetrakis(4-carboxyphenyl)porphyrinato Zn(II) (c) and meso-tripyridyl(4-carboxyphenyl)porphyrinato Zn(II) (d) is reported here, in terms of current-potential curve, open-circuit potential, fill factor, and overall solar energy conversion efficiency which have been evaluated under 100 mW/cm² light intensity and their performances compared to the benchmark N719 (di-tetrabutylammonium cis-bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato) ruthenium(II)). This work focus the structural aspects of dyes with anchoring groups using TiO₂-based Dye Sensitized Solar Cells (DSSCs), which includes pyridyl and carboxyphenyl acid groups and argue how the combination of both anchoring groups, in the same structure, may allow relevant optimization of DSSCs performance in the near future.

Also, a noticeable improvement in the photovoltaic performance of all dyes, reaching a maximum increase from 25% to 69% in the overall DSSC efficiency under short periods of white light illumination is discussed.

四种锌金属卟啉染料的敏化活性：内消旋-四（4-吡啶基）卟啉对Zn（II）（a），内消旋-三苯基-（4-羧基苯基）卟啉对Zn（II）（b），内消光-四（4-）此处以电流-电位曲线，开路电位，填充系数和总太阳能为依据，报道了羧基苯基）卟啉锌（c）和内三吡啶基（4-羧基苯基）卟啉锌（d）已在100 mW / cm ^2的光强度下评估了其能量转换效率，并将其性能与基准N719（二-四丁基顺式双（异硫氰酸根）双（2,2'-联吡啶基-4,4'-二羧甲基）钌（II））。这项工作着眼于使用基于TiO ₂的染料敏化太阳能电池（DSSC）的具有锚定基团的染料的结构方面，该染料包括吡啶基和羧苯基酸基团，并讨论了在相同结构中两个锚定基团的组合如何允许相关的优化。 DSSC在不久的将来的表现。

此外，还讨论了所有染料在光伏性能方面的显着提高，在短时间白光照射下，总DSSC效率从25％增至69％。
