Abstract: Quantum dots-sensitized solar cells have been regarded as one of the most potential photovoltaic candidates owing to the lower cost of fabrication as well as the higher theoretical efficiency. And their outperformance mainly depends on the involving photoanode, quantum dot sensitizers, electrolyte and counter electrode. Therefore, the collaborative optimization of the four parts mentioned above becomes the most direct way to improve the photoelectric conversion efficiency of this kind of photovoltaic device. This paper reviews the recent advances in the four parts of the quantum dots-sensitized solar cells. Finally, the possible development directions in the future for the fabrication of high-efficiency and practical quantum dots-sensitized solar cells are put forward.
Key words: solar cells; photoanode; quantum dot sensitizers; electrolyte; counter electrode; photoelectric conversion efficiency
