Embodiment

[0032] In this embodiment, the photon radiation heat dissipation structure that needs to be prepared has a period of 12um, and the height of the pyramid in the periodic unit is about 8.47um. The ratio of the pyramid structure to the unit period is 0.9. The material is silicon dioxide. The radiation heat dissipation structure is applied to traditional commercial solar cells.

[0033] The periodic pyramid structure is prepared on a single crystal silicon substrate: a layer of AZ6112 resist film is coated on the surface of the crystalline silicon with an oxide layer by spin coating, assembled on a mask, exposed by a photolithography machine, and passed Development realizes the transfer of the mask pattern to the resist film. Use BOE solution to etch the silicon oxide layer to realize the transfer of the mask pattern to the silicon oxide layer. Using silicon dioxide as a mask, an etching solution was prepared according to the ratio of deionized water: potassium hydroxide: isopropano...

Description

Technical field [0001] The invention relates to the field of radiation heat dissipation, in particular to a photonic structure for radiation heat dissipation. Background technique [0002] Solar equipment is exposed to sunlight (energy density is 800W / m) under the condition of temperature of 300K (about 27℃) 2 ), the surface temperature of solar equipment that has not taken cooling measures will be much higher than the ambient temperature, and long-term working temperature will cause the power of the equipment to drop, and the aging rate will double. [0003] Traditional solar energy equipment cooling strategies, including heat transfer to the heat dissipation surface, forced convection, air cooling, water cooling, heat pipe-based cooling systems and micro-channel cooling technology, mainly focus on the use of non-radiative heat transfer pathways for engineering design heat conduction or convection methods . These heat conduction or convection cooling technologies either require a...
