Investigation of 'Keriang' fruit Dye application on the performance of Dye-Sensitized solar cell with anatase-rutile TiO Electrode

Dye-sensitized solar cell (DSSC) or 'Gratzel cell' is a low-cost solar cell from the thin film family which consists of TiO electrode coating, sensitizer from dye molecules soaked in the TiO film, a mediator electrolyte layer, and a counter electrode. This paper focuses on fabricating dye-sensitized solar cell (DSSC) with anatase and anatase-rutile mixture of nanocrystalline TiO at varied thickness sensitized with high light-absorbing nature dye and an alternative conductive counter electrode catalytic material. This paper proposes on the potentials of 10\ {\mu}\mathbf{m} thickness of rutile-anatase (RA) with a 1:4 ratio concentration, absorbed into a high concentration anthocyanin from 'keriang' fruit extract and by the use of carbon as a counter electrode. This arrangement shows the highest solar cell efficiency at 1.16% with higher short circuit current of 5.5 mA/cm and fill factor of 0.55 which is the highest among overall experimented nature-based solar cell.
