Fabrication And Characterization Of Dye Sensitized Solar Cells (Dsscs) Using Natural Dyes Obtained From Leaves Of Xanthosoma Saggitifolum, Mimosa Pudica, Delonyx Regia And Dacryodes Edulis :- Ujoatuonu, Amaka L
ABSTRACT
Different
natural dye extracts were prepared and used as sensitizers in the fabrication
of dye sensitized solar cells (DSSCs). In this work, prior to the sprayed
nanoporous TiO2 layer on Fluorine doped oxide
(FTO) glass, a dense layer of TiO2 of ~60nm in thickness as an electron blocking layer
was deposited directly onto the FTO using spray pyrolysis technology. Scanning
electron microscopy (SEM) and X-ray diffraction (XRD) analysis showed some
porosity in the sprayed films for the mesoporous layer, and dense structure
demonstrating good blocking characteristics. This suggests the presence of
small voids rather than pinholes in the deposited films. Finally, the
absorption spectra of these DSSCs sensitized with these dyes have been
investigated by UV-Vis spectrophotometry. Photovoltaic parameters such as short
circuit current density Jsc, open circuit voltage Voc, fill factor FF, shunt
resistance and overall conversion efficiency
gaps
were obtained using Tauc relation, result showed approximate value of
0.0
