"Photovoltaic response of Carissa spinarum berry extract in dye-sensitized solar cell".

The presented work deals with the titanium dioxide semiconductor-based dye-sensitized solar cell (DSSC) performance analysis. The DSSC is sensitized with natural dye extracted from Carissa spinarum fruit with iodide-Tri-iodide as an electrolyte and graphite coated transparent conducting oxide as back electrode. The dye characteristics were investigated by Fourier transform infrared, ultraviolet-visible, and photoluminescence spectroscopy to study the associated functional groups, optical band gap, and emission, respectively.
