Problems solved by technology

However, because the energy level transition spectrum of rare earth ions is narrow line-shaped, the spectral line intensity is low, and the matching degree with the solar spectrum is low, resulting in low luminous efficiency of near-infrared quantum tailoring materials, which limits its application as a light conversion film. prospect

Description

technical field [0001] The invention belongs to the technical field of rare earth luminescence, and in particular relates to a gold nano-array substrate and its composite structure with a near-infrared quantum tailoring luminescent material and a preparation method. Background technique [0002] Solar energy is a green, pollution-free energy. The most common device that harnesses the power of the sun today is a solar cell, which converts light energy into electricity. Although the solar cell industry is developing rapidly, the efficiency of solar cells is still low. The main reason for the low conversion efficiency of solar cells is that the incident photons do not match the bandgap energy of the solar cell. Photons with energy lower than the bandgap energy of the solar cell cannot be absorbed, while photons with energy higher than the bandgap energy of the solar cell are converted into thermal energy. The loss of the form leads to a very low utilization rate of solar ener...
