摘要： Provided are an organic rare-earth solid micelle and a preparation method therefor, and a method for improving the photoelectric conversion efficiency of a solar cell. A small organic conjugate ligand is used as a first ligand; a diblock polymer with amphipathy is used as a second ligand; and the two are mixed and doped with a rare-earth element chloride solution, and self-assembled so as to form an organic rare-earth solid micelle. Thereby the fluorescence emission intensity and the fluorescence efficiency of the rare-earth element are improved. Next, the prepared organic rare-earth solid micelle is spin-coated on an ITO layer of a solar cell, such that a solar cell with the organic rare-earth solid micelle is prepared. Thus the sunlight absorption of a cell can be increased, and the photoelectric conversion efficiency is improved. The preparation process is simple, low in cost, high in photoelectric conversion efficiency and environmentally friendly.
