Dye Sensitized Solar Cells (DSSCs) are a class of solar cells that use a photosensitive dye to absorb light and produce electricity. Unlike traditional silicon-based solar cells, DSSCs are made from inexpensive materials and can be manufactured using simple techniques. They consist of a porous layer of titanium dioxide (TiO2) nanoparticles, coated with a molecular dye that absorbs sunlight and generates electrons.
