2. What is a dye sensitized solar cell? What is a dye sensitized solar cell? It is a kind of battery that derives its energy from the light energy received from the lamp or.... the sun!

3. What does a dye sensitized solar cell consist of? A dye sensitized solar cell consists of two conducting glass electrodes  electrode (1) is coated with a thin layer of titanium dioxide stained with the dye which produces electrons by photo excitation  electrode (2) is coated with graphite carbon layer which helps the transfer of electrons through the iodide electrolyte back to electrode (1) in a sandwich arrangement with an iodide electrolyte. TiO 2 /dye molecules electrode (1) Graphite electrode (2) Iodide electrolyte

17. Why a dye sensitized solar cell instead of the traditional solar cells? Low-cost materials and low manufacturing cost. Works effectively in low lighting conditions. Less susceptible to losing energy to heat.
