The invention discloses a method for manufacturing a rare-earth sulfide quantum-dot solar cell and application of the rare-earth sulfide quantum-dot solar cell. Rare-earth sulfide quantum dots are successfully compounded through characteristics of a solvothermal method and a hydrothermal method, the particle sizes of the quantum dots are adjusted by changing the reaction temperature and the reaction time, the crystal forms of the quantum dots are adjusted by controlling the hydrothermal time and the hydrothermal temperature to enable a p-type semiconductor and an n-type semiconductor of the solar cell to be matched in energy level, and the photoelectric conversion efficiency of the solar cell is improved. The method and the application have the advantages that the rare-earth sulfide quantum dots are stable in manufacturing technology, large in quantum-dot-fluorescence peak width at half height, the manufactured solar cell is easy to assemble, low in cost, wide in absorption spectrum and high in photoelectric conversion efficiency, and has the high development value.
