Cost and energy payback time in relation to solar cell performances is one of the key parameters considered for mass application. In this research work, a low-cost, easily fabricated, and the more eco-friendly photovoltaic device was successfully developed using the dye synthesized from teak plant leaves. The dye-sensitized solar cell (DSSC) is made up of photoelectrode and counter electrodes. The photoelectrode was prepared by depositing zinc paste on an active area of 1cm2 of an Indium tin oxide (ITO) glass. The glass was annealed at a temperature of 4500C for 30 minutes and stained in a beaker containing teak dye (a dye extracted using ethanol) for 24 hours. Another ITO glass was placed some centimeters above a candle flame to form the counter electrode; the effect was a dark-shaded ITO glass. To have working DSSCs, a binder clip was introduced to couple the two electrodes and three drops of iodine (as an electrolyte) were dropped in between the electrodes to complete the fabrication process. The ethanol-extracted dye has an absorption spectrum of 342 nm at a small peak and a broad absorption wavelength in the range of 412-664 nm. The power conversion efficiency (ƞ) of 0.44% was achieved through the developed solar cell.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
