Description
Summary:Dye-sensitized solar cells still offer an encouraging option in the photovoltaic family. It is endowed with several attributes such as ability to generating green energy at low cost, ease of fabrication and yearlong availability of raw materials. Betalain an important constituent of B.vulgaris shows diverse changes to temperature and solvents as they alter the fluidity of its membrane. This experiment seeks to explore the latter with a keen interest on the IPCE and efficiency of beetroot dye-sensitized solar cells (DSCs). The Doctor blade method of application of TiO2 photoanode using ethanol as precursor and high temperature sintering reveals diverse spectral responses in the efficiency of the DSCs with the most efficient B.vulgaris dye recording 0.27% and the highest IPCE of the dye revealed as 28.34%.
