A comparative study: synthetic dyes as photosensitizers for dye-sensitizedsolar cells

Özet

In this paper, dye-sensitized solar cells (DSSCs) were fabricated using a zinc oxide (ZnO) semiconductinglayer and different synthetic dyes. Eight different synthetic dyes were used to fabricate the DSSCs. NanocrystallineZnO powder was coated on transparent conducting uorine-doped tin oxide glass using the doctor blade method toform a thin layer. The absorption spectra of the synthetic dyes were investigated. DSSCs were characterized withJ-Vcharacteristic curves. The parameters re ecting the cell performance were calculated. The results revealed that eosin Ydye corresponds to the highest conversion efficiency. The dependence of the sintering temperature and the thicknessesof the ZnO layer on the performance of the cell was investigated.
