Abstract

The invention provides a photo-thermal conversion structure, a preparation method thereof and a solar distillation device. The preparation method of the photo-thermal conversion structure comprises the following steps that firstly, printing paper and non-woven fabric are provided; secondly, the non-woven fabric is laminated on the surface of the printing paper so as to form a permeable matrix layer; thirdly, a photo-thermal material is printed on the surface, away from the printing paper, of the non-woven fabric through a printer so as to form a photo-thermal material layer which is arranged in a laminated mode with the permeable matrix layer; and fourthly, the part, which is not printed, of the non-woven fabric is removed so as to obtain the photo-thermal conversion structure.

Description

technical field [0001] The present application relates to the field of light-to-heat conversion, in particular to a light-to-heat conversion structure, a preparation method thereof, and a solar distillation device. Background technique [0002] With the development of economy, water pollution is becoming more and more serious. The scarcity of fresh water resources has become one of the most serious challenges in the world. Seawater desalination has attracted people's attention as a clean and sustainable way to obtain fresh water. Using solar energy to directly evaporate seawater is an effective method for seawater desalination and desalination, and this method does not require additional energy supply, and meets the requirements of energy saving, emission reduction and sustainable development. Usually, the photothermal conversion structure is used to convert solar energy into heat energy, and the converted heat energy can act on seawater to evaporate it, so as to realize d...
