Fabrication of Organic Dye Sensitized Solar Cell

Article Preview

Abstract:

Renewable energy is rapidly gaining importance as an energy resource to help aid the national energy depletion crisis of fossil fuel and coal. One of the most potential renewable energy sources in Malaysia is hydropower followed by solar energy. This paper presents the fabrication of Dye Sensitized Solar Cell (DSSC) using organic dyes from dragon fruit and chlorophyll which is extracted from spinach. The fabrication of DSSC uses the Dr.blade method. Result shows that the efficiency by using dragon fruit as sensitizer at 40µm TiO2 Thickness is 6.45%, better than the usage of chlorophyll dye which is 4.23% at the same thickness. Result also shows that at 80µm by using the dyes from chlorophyll extract has higher solar cell efficiency compare to dragon fruit. This shows that both the chlorophyll extract and dragon fruit shows potential in the development of a feasible working organic dye.
