Natural Dye Extracts of Areca Catechu Nut as dye Sensitizer for Titanium dioxide Based Dye Sensitized Solar Cells

摘要

A dye sensitized solar cell was fabricated using titanium dioxide nano particles sensitized by a newudnatural dye extracted from areca catechu nut. The natural dye extract contains tannin which is rich in gallotannicudacid. The pure titanium dioxide nano particles in anatase phase were synthesized by sol-gel techniqueudand were sensitized by the natural dye to yield photo anode material. The Powder X-Ray Diffraction,udUV-vis spectra, Fourier Transform Infra Red spectroscopy, Energy Dispersive X- Ray spectroscopy andudScanning Electron Microscopy studies of pure and natural dye sensitized TiO2 were carried out to analyzeudtheir structural, optical, functional group, compositional and morphological details. The dye sensitized solarudcell was fabricated using TiO2 nano particles coated on FTO glass plate which is sensitized by the naturaluddye as photo anode and platinum coated FTO as counter electrode. The natural dye sensitized solar celludshowed a solar light energy to electron conversion efficiency of 0.76 %.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35814
