Dyes are used in a dye-sensitized solar cell to convert radiant energy of light to electrical energy. The structure shown in the graphic allows students to clearly recognize the differences from the structure of a solar cell made of semiconductor material. It also shows how free electrons are released when the dye molecules are excited and the resulting electron flow in the cell.

The cell structure can be labeled individually or as a whole. In either case, the electron flow can be followed step by step.
