Abstract

In this work, dye sensitized solar cell employing commercial TiO2 as photoanode was fabricated using natural dye pigments obtained from Brassica oleracea (Green Cabbage) as the photosensitizer. UV-VIS spectrophotometry was used to determine the optical properties of the dye. Experimental results show that for this cell, the open-circuit voltage (VOC) was found to be 0.246 V, the short-circuit current density (JSC) was 0.193 mA/cm2, fill factor (FF) was obtained as 0.413 and power conversion efficiency (η) was 0.0196%. Absorption spectra for the extract show small peaks at 336 and 605 nm, with the optimal peak at 665 nm. The result suggests that while a Brassica oleracea-sensitized solar cell is possible, it is a poor source of chlorophyll and has limited viability as a photosensitizer for the manufacture of DSSCs.
