In recent years, quantum dots (QDs) have attracted significant attention because of their unique optoelectronic properties such as band gap tunability, high absorption coefficient, and potential for multiple exciton generation. Especially, owing to these attractive properties, QDs have been regarded as a promising material for solar energy conversion, including solar cells and photoelectrochemical (PEC) water splitting. This presentation will discuss the application of quantum dots for the PEC water splitting as a photosensitizer. Firstly, the fabrication technique and application of highly loaded PbS/Mn-doped CdS QDs on a mesoporous TiO2 electrode will be introduced. Secondly, the application of copper-indium-selenide (CISe) ternary QDs to the PEC water splitting will be introduced. In particular, the effects of ZnS overlayer on the CISe QD-sensitized TiO2 electrode will be discussed |
