Abstract: The emergence of quantum dot-sensitized solar cells (QDSSCs) has provided an alternative way to harvest sunlight for energy conversion. Among all the QDSSCs, cadmium chalcogenide (CdX, X=S, Se or Te) based QDSSCs have gained a significant interest due to their easy fabrication, low cost and high performance. However, their performance still does not match with that of their dye-sensitized solar cells (DSSCs) counterpart. In this review, the concept and mechanism behind the QDSSCs are reviewed. Fabrication methods and possible approaches for improving the Cd chalcogenide QDSSC performance are also discussed. It is worthwhile to note that the efficiency of a QDSSC depends on the fabrication method of the quantum dots, morphology of the photoanode, type of electrolyte used and the choice of the counter electrode. It is therefore, imperative for engineering of materials and optimization of the fabrication method for the improvement of QDSSCs performance.
