Solar cell using sensitizer extracted from organic substances

Renewable energy is rapidly gaining importance as an energy source that supports conventional energy from the deteriorating fossil fuels and coals. DSSC is another type of solar cell which has an advantage as low cost, easy to fabricate and is clean from contamination. This project presents the fabrication of Dye Sensitized Solar Cell (DSSC) using organic dyes from dragon fruit and spinach extract (chlorophyll) Fabrication of DSSC uses conventional Dr. Blade´s method and measurement of DSSC is tested under halogen lamp as the light source for solar cell. Results shows that by using dragon fruit as sensitizer, the solar cells efficiency is 4.07% which is better than the use of chlorophyll dye which is 3.60%.
