Dye-sensitized Solar Cells: Materials and Processes

چکیده
The dye-sensitized solar cell (DSSC) has been proven to have a good chance to become a notable competitor for solar cells based on today technology of p-n junction. The principle of operation of DSSC solar cells in comparison with conventional semiconductor solar cells where light absorption and charge carrier transport are done by the semiconductor is different. In DSSC these two tasks are separate. Charge separation is done by photo-induced injection to the conduction band and such created carriers are transported to charge collector. By using dyes which have broad absorption band, the solar cell is capable to harvest large fraction of sunlight. In this paper the basic construction and mode of operation of solar cells based on dyes is described.
