Study on Preparation of CdS Quantum Dots for Dye Sensitized Solar Cells

Quantum dot sensitized solar cell (QDSSC) has a potential high efficiency as the third generation solar cell, on account of the excellent performance of quantum dots. CdS is one of the most widely used quantum dot of QDSSCs, hence the optimization of its preparation process is extremely important. CdS quantum dots prepared in aqueous or alcohol on TiO2 film by successive ionic layer adsorption and reaction (SILAR) method are investigated and alcohol is found to be better than water as the precursor solvent.
