Abstract

Chlorophyll and carotenoid are pigments used by photosynthetic organisms as light harvester. Chlorophyll and carotenoids are abundantly available nature and can be found in the roots, stems, leaves, and fruit, as well as photosynthetic bacteria. As an efficient light harvester, chlorophyll and carotenoid may become potential candidate as sensitizers in dye sensitized solar cell using Gratzel construction (Dye sensitized solar cell, DSSC). The mixture of carotenoid and chlorophyll as sensitizers in DSSC may have higher efficiency than that of carotenoids or chlorophyll alone as sensitizers. This research reports the results of DSSC construction using a combination of B-carotene and chlorophyll as sensitizers. The combination of chlorophyll and B-carotene has Voc output 14,1 mV and Jsc 5,76 uA/cm2 with efficiency up to 4,42 × 10^-5 %.
