摘要：

Dye-sensitized solar cells (DSSCs) have been constructed using fluoride tin oxide (FTO) glass deposited with TiO2 and anthocyanin dye extracted from blackberries as the photoanode, platinum coated cathode, and gel polymer electrolytes (GPEs) comprising poly(vinyl alcohol) (PVA) dissolved in two different solvents, viz., dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO). GPE employing DMF solvent exhibits the highest ambient conductivity of 14.05 mS cm(-1). Charge transport properties of DSSCs were studied via intensity-modulated photocurrent spectroscopy (IMPS), intensity-modulated photovoltage spectroscopy (IMVS) and electrochemical impedance spectroscopy (EIS). The highest efficiency of 0.54% is recorded for DSSC with GPE containing DMF and TBP.
