Electrical Performance of Dye Sensitized Solar Cell with the Extracts of Swamp Land Vegetation as Organic Dye Sensitizer

Abstract

The electrical performance of dye sensitized solar cell with the extract of swamp land vegetation was conducted based on the extracts of bluebell (Ruellia tuberosa L.), flowers of ulam raja (Cosmos caudatus Kunth), and leaves of water spinach (Ipomoea aquatica). The electrical characteristics of DSSC was different for each dye sensitizer. The difference in electrical characteristics of DSSCs in the range of lighting source intensity 445 W/m2 - 845 W/m2 generated from solar lighting sources is generally higher than that generated from halogen lamp. Efficiency (η) of the conversion of light into electricity produced by DSSCs whose lighting sources from halogen lamps tend to decrease with the decreasing intensity of lighting sources, except for extract leaves of water spinach. The efficiency of the conversion of light into electricity produced by DSSC for extract leaves of water spinach on halogen lamps with the intensity of lighting sources 445 W/m2, 205 W/m2, and 100 W/m2, respectively 0.284%; 0.483%; and 0.983%.
