Study of dye sensitized solar cell using canna lily sensitizer nanocrystalline titanium dioxide photoanode

Abstract

In the present work, dye sensitized solar cell is fabricated using canna lily as sensitizer on nanocrystalline TiO2 photoanode. TiO2 photoanode film is deposited on transparent fluorine doped tin oxide (FTO) substrate using doctor blade method. Using UV-Vis spectrometer, SEM, optical absorption analyses and photovoltaic characterization is carried out for Canna lily sensitized photoanode. The DSSC is fabricated by assembling canna lily sensitized photoanode and graphite coated counter electrode. The photoelectrochemical performance of the canna lily flower dye extract showed an open circuit voltage (Voc) of 1.6 mV, short circuit current 18 mA Fill factor, and conversion efficiency 0.20%.
