Review on the efficiency of quantum dot sensitized solar cell: Insights into photoanodes and QD sensitizers

With available different solar cell technology, adequate conversion efficiency is a major concern with reference to important parameters like energy payback time, inexpensive to fabricate: Production cost, lightweight, customizable, flexible, less adverse environmental effects. Such solar cells are developed using a modern version of dye synthesized solar cells and progress in nanotechnology known as quantum dot sensitized solar cells (QDSCs). QDSCs attracted researchers due to their high absorption coefficient, tunable bandgap, multiple exciton generation, and fabrication method, and energy payback time. Currently in the laboratory achieved efficiency of QDSCs is 18.1% in comparison to theoretical limits. This review article presents a comprehensive overview of the efficiency of QDSC and its status under the effect of photoanode and Quantum Dot sensitizers.
