Infrared unidirectional light-trapping plate, manufacturing method, photobioreactor and photosynthetic bacterial culture method

Abstract

The application discloses an infrared one-way light-trapping plate, a manufacturing method, a photobioreactor and a photosynthetic bacterial culture method, and belongs to the technical field of microbiology devices. The infrared one-way light-trapping plate comprises, from outside to inside, an incident matching layer, a light-guiding base layer and a total reflection blocking layer. The incident matching layer comprises a base body and a bionic moth-eye nano array distributed on the outer surface of the base body. The light-guiding base layer is an optical medium, the refractive index of the optical medium is greater than the refractive index of the incident matching layer, and the refractive index of the total reflection blocking layer is lower than the refractive indexes of the light-guiding base layer and the inner medium. The application has the advantages of intercepting escaped light energy and eliminating interface reflection loss.
