Done by Group: Wakrag_Silver8 School: Al Wakra Independent School for Girls Dye-Sensitized Solar Cells (DSSC) Module: The students study the concept of using dyes to plant dyes to capture the solar energy to convert it into electrical energy simulating the natural process “photosynthesis”. They use the workshop-gained knowledge in DSSC to invent new products. The project consists of using two dyes. Then, it demonstrates the ides of designing LED system for street lights using DSSC.
