2024年6月1日 · In cocktail dye applications in DSSCs, when TiO 2 semiconductor-coated photoanodes are immersed in dye mixtures, YD2 porphyrin and NPc dyes of different shapes and sizes self-arrange on the TiO 2 surface through effective adsorption thanks to the anchor groups they have, forming a molecular layer that can absorb the incoming light well.

2018年3月5日 · YD2 is a green zinc-centered porphyrin dye used as a sensitizer for dye-sensitized solar cells (DSSCs). 1) Although ruthenium-based dyes such as N719 dye and N749 black dye are well known as efficient sensitizers, ruthenium-free sensitizers including porphyrin dyes have also been developed as they do not need to contain any noble metals, which ...

The IS results provide key information related to the device performance for a highly efficient porphyrin dye (YD2), a reference porphyrin dye (YD0), and a commercial ruthenium dye (N719). The DSC devices constructed using YD2 and N719 dyes reach similar internal power conversion efficiencies (7.41% vs 7.54%) due to the higher injection of the ...

These newly synthesized mono carboxylic acid substituted non-symmetrical zinc(II) phthalocyanines were mixed with a porphyrin-based YD2 dye at miscellaneous ratios to obtain new cocktail dyes as efficient sensitizers for DSSC.

2016年8月5日 · Porphyrin YD2-o-C8-based dyes were employed to sensitize room-temperature (RT) chemical-assembled ZnO aggregated anodes for use in dye-sensitized solar cells (DSSCs). To reduce the acidity of the YD2-o-C8 dye solution, the proton in the carboxyl group of a porphyrin dye was replaced with tetrabuthyl ammonium (TBA+) in this work.

2018年3月5日 · yd2是一种以锌为核的绿色卟啉染料，可用作染料敏化太阳能电池(dsscs)的光敏剂 1) 。尽管众所周知的有效的光敏剂是含钌染料如n719染料和n749黑染料等，不含钌的光敏剂包括卟啉染料也被开发出来，这类光敏剂不含任何贵金属，因此可以降低材料成本。

2015年8月13日 · The interaction of the dye YD2 with a cluster of (anatase-phase) TiO 2 (which is utilized in dye-sensitized solar cells, DSSCs) and electron injection by the dye into the cluster were studied by performing density functional theory (DFT) calculations at the B3LYP, PBE, and TPSS levels of theory, including dispersion effects.

2023年6月1日 · In order to increase the solar absorption range, dye cocktails have been prepared with the Pcs and YD2 por dye. The best conversion efficiencies were found to be 9.96% (YD2 + ZnFPNPc) and 10.72% (YD2 + TiOFPNPc) with cocktail dye (3:1). The champion DSSC achieves 10.72% under sun and retains 98% of its initial value after 24 h.

To fabricate highly efficient dye sensitizers for dye-sensitized solar cells, new zinc porphyrin dye sensitizers were designed based on one of the most efficient dyes, YD2-o-C8, by...

The interplay between the different channels involved in the dye-sensitized solar cells (DSSCs) photodynamic cycle (photon absorption, dye aggregation and emission quenching, e – injection, dye regeneration, e – –dye recombination) is the determining factor …
