Sensitized Solar Cells

The solar energy is the most promising energy to solve energy crisis and environmental problem. Quantum dot can be applied to solar cells in two structures of QDSC to improve the energy conversion efficiency. The two structures are p-i-n type QDSC and quantum dots sensitized solar cells. The energy conversion efficiency of p-i-n type QDSC may increase up to 45%. Both CdSe and CdS quantum dot can be used as the sensitizer of the QDSSC and each of them has its demerits and merits, but the conversion efficiency of QDSSC is low if they were used respectively. Thus, in order to overcome their demerits respectively, we could try to combine their merits. QDSC is the most promising technique to solve the problems of solar cell. But before large-scale application their efficiency and stability should be improved.
