Abstract

The invention relates to the field of solar power generation and particularly relates to a fluorescence waveguide light condensation module, a solar power generation device and application thereof. The fluorescence waveguide light condensation module comprises two opposite glass waveguide layers, a fluorescencelight condensationwaveguide layer and a reflection layer, wherein the fluorescencelight condensationwaveguide layer and the reflection layer are successively arranged between the two glass waveguide layers; the light condensationwaveguide layer comprises two fluorescence layers and an optically thinner medium layer arranged between the two fluorescence layers; the optical density of the optically thinner medium layer is smaller than that of the fluorescence layers. The invention also provides the solar power generation device and the application thereof. The solar power generation device with high sunlight utilization rate is produced by connecting the fluorescence waveguide light condensation module with a photoelectric conversion element; the solar power generation device can be used as building glass. The fluorescence waveguide light condensation module and the solar power generation device have the advantages of simple structure, simple preparation process, low production cost and high sunlight utilization rate.

Description

【Technical field】 [0001] The invention relates to the field of solar power generation, in particular to a fluorescent waveguide light concentrating module, a solar power generation device and applications thereof. 【Background technique】 [0002] The fluorescent waveguide concentrating module based on spectral conversion is a new type of solar concentrating device, which gathers sunlight through the optical waveguide containing phosphor powder, thereby reducing the use of solar panels and improving the power generation efficiency of solar panels. The core of the fluorescent waveguide concentrating module is the fluorescent concentrating waveguide. The core that affects the fluorescent light-concentrating waveguide lies in the design of the waveguide and the optical properties of the fluorescent layer. [0003] The general fluorescent waveguide concentrating module needs to mix fluorescent materials into the waveguide, which has special requirements for fluorescent materials,...
