ENHANCING DSSC EFFICIENCY WITH CONDUCTING PPY/GO -DECORATED COUNTER ELECTRODES AND PHOTOANODE SENSITIZED BY NATURAL DYES

This research is to study the preparation of conducting polymer decorated Ppy/GO composite material for uses as hybrid counter electrode in dye sensitized solar cell. It started with the synthesis of Ppy/GO composite and X ray,  SEM characterization has been studied, followed by the preparation of counter electrode, exaction of dyes from the the seeds of Bixa Orellana, flower of Cannal lily, Fruits of Basella Alba for preparation of photoanode. Using UV- vis spectrometer, optical properties has been studied out for all the extracted dyes. DSSC is fabricated by assembling extracted dye sensitized photoanode and Ppy/GO coated counter electrode. The photovoltaic characteristics had been studied and efficiency of DSSC is calculated, results obtained for dyes from the fruits of Basella Alba, flower of Cannal lily, seeds of Bixa Orellana respectively as an open circuit voltage (Voc) of 17mV, 18mV, 18mV, Short circuit current 167mA, 183 mA, 173mA, Fill factor 0.42, 0.54, 0.55 and conversion efficiency 0.164, 0.246, 0.24.
