Dye Sensitized Solar Cells by Using Natural Dyes Anthocyanin Dye Extracted from Red Cabbage and Chlorophyll Dye Extracted from Palm Leaf as Photosensitizer

Abstract

In this work of Dye-sensitized solar cells (DSSCs) were fabricated using Nano particle titania (TiO2) (deposited on ITO glass) as photo anodes and carbon counter electrode, sensitized dye were natural dye anthocyanin dye was extracted from red cabbage and chlorophyll dye was extracted from palm leaf and the electrolyte (I-/I3-). The absorption spectra of natural dye was investigated by UV-Visible spectroscopy which showed that the beetroot dye and palm leaf absorbed light at 550 nm and (664,420) nm respectively. The efficiency of prepared DSSCs were estimated through I-V characterization, the fall factors (ff) and electrical conversion efficiencies (ᵑ%) were measured using potentiostat. The conversion efficiency of chlorophyll and anthocyanin was 0.892%, 0.502% respectively.
