Dye-sensitized solar cells fabricated with black raspberry, black carrot and rosella juice

In this work, dye sensitized solar cells (DSSC’s) were constructed from black raspberry ( Rubus Ideaus ), black carrot ( Daucuscarota L.) and rosella juice ( Hibiscus Sabdariffa L. ). In order to fabricate a DSSC the fluorine-doped tin (IV) oxide (FTO) thin films obtained by using spray pyrolysis technique were used as a substrate. TiO 2 films on FTO layers were prepared by doctor-blading technique. Platinum-coated counter electrode and liquid Iodide/Iodine electrolyte solution were used to fabricate DSSC’s. The efficiencies of solar cells produced with black carrot, rosella and black raspberry juice were calculated as 0.25%, 0.16% and 0.16% respectively, under a sunny day in Kahramanmaraş-Turkey.
