A three-electrode integrated photo-supercapacitor utilizing graphene-based intermediate bifunctional electrode

A dye-sensitized solar cell (DSSC) employing a compact and mesoporous titania (TiO2) film as the anode was integrated with a symmetrical supercapacitor utilizing polypyrrole/reduced graphene oxide (PPy/rGO) electrodes to form a photo-supercapacitor. The double-sided-electrodeposited PPy/rGO material...
