Recent advances in quantum dot-sensitized solar cells: insights into photoanodes, sensitizers, electrolytes and counter electrodes

摘要: Quantum dot-sensitized solar cells (QDSCs), as promising candidates for cost-effective photoelectrochemical cells, have attracted much attention due to their characteristic properties such processability at low cost, feasibility control light absorption spectrum in a wide region, and possibility of multiple electron generation with theoretical conversion efficiency up 44%. QDSCs analogous structures dye-sensitized typically consisting semiconductor photoanodes sensitized quantum dots (QDs), redox electrolytes, counter electrodes (CEs). Much effort has been dedicated optimizing each component higher device performance. In this review, recent advances various architectures, QDs tunable band gaps, electrolytes liquid, quasi-solid or solid state, CEs great electrocatalytic activity will be highlighted. We aim elaborate the rational strategies material design QDSC applications. Finally, conclusion future prospects emphasize key developments remaining challenges QDSCs.
