Description

Technical field

[0001] The invention relates to a nano fluorescent particle doped with rare earth element ions and the use of the nano particle in a solar cell. Background technique

[0002] The rapid development of global technology and economic activities has led to a surge in human energy demand, and the phenomenon of insufficient energy in the future has emerged. The environmental pollution caused by the use and discharge of fossil fuels has become a major issue that cannot be ignored in countries all over the world. The inexhaustible and inexhaustible solar energy is a clean, renewable and green energy. Solar power generation technology is conducive to purifying the environment and reducing pollution. It is an important way for mankind to fundamentally solve energy problems. However, the photoelectric conversion efficiency of solar cells is low, and the cost of power generation is too high, which is called a bottleneck restricting the wide application of solar power. The ...
