Use fruit to build a dye-sensitized solar cell (DSC) and measure its electrical characteristics. The DSC is built using conductive glass plates as supports for the anode and the cathode. The anode is nanocrystalline titanium oxide that is stained with a dye to absorb visible light, and the cathode is graphite. The cell is filled with an iodine/iodide electrolyte solution that acts as a redox catalyst. This lab introduces students to a huge number of chemistry topics including materials chemistry, alternative energy, solid state chemistry, electrochemistry, sustainability, green chemistry and nanotechnology. Moreover, students observe the direct application of chemistry, as they see evidence for light's conversion to electricity. This experiment, developed in partnership with Beyond Benign, will bring chemistry from the abstract into students' everyday world. Includes reproducible student handouts, Teacher Notes, and all necessary chemicals. Complete for 24 students working in groups of 4.
