Abstract
Photosupercapacitor (PSc) was an integration of photovoltaic as a device for harvesting light energy and supercapacitor as an energy storage device. Multifunctional harvesting device has increasing demand in the green energy industry sector. In this study, we demonstrate the integrated array of photovoltaic type dye-sensitized solar cell and carbon-based supercapacitor. The photosupercapacitor integration will be arranged in a different arrangement, called sandwich and parallel arrangement. DSSC photoanode was used TiO2 material that deposited using screen printing method on FTO substrate. Activated Carbon/Carbon Black/SBR as material composite of electrode was deposited on the aluminium foil substrate using dr. blade technique. XRD characterization has identified the pure anatase phase in the TiO2 photoanode. Mesoporous morphology of TiO2 was identified by SEM characterization. The Ti element of photoanode has identified by EDX of 64.23 wt%. The UV Vis spectroscopy curve has identified the absorbance of TiO2 photoanode in the wavelength range of 290 - 460 nm. The J-V characterization shows that TiO2 photoanode has power conversion efficiency of 0.85%. The I-V characterization of photosupercapacitor performance was arranged by sandwich and parallel. The photosupercapacitor was treated with light and dark under light illumination of 100 mW.cm-2. The performance of photosupercapacitor sandwich has shown higher the parallel arrangement.
