In the ongoing pursuits for efficient photoelectrochemical (PEC) cell for solar generation of hydrogen via splitting of water, quantum dots (QDs) sensitization on photoelectrodes have emerged as promising technique. Present review discusses the operation and principle of QDs sensitized PEC cell (QD-SPEC) along with the status of the worldwide research in this domain. Method of sensitization, nature of QDs, quantity and size-dimensions of QDs, the nature and morphology of basic photoelectrodes are the important factors that govern the hydrogen generation rate in QD-SPEC systems. All these factors along with their effect on the efficiency of the QD-SPEC system have been critically examined and presented.
