Description

technical field [0001] The invention belongs to the field of solar photothermal conversion, and relates to a solar selective absorption coating, a preparation method and an application. Background technique [0002] At present, the energy utilization of solar energy mainly includes three ways: photothermal conversion, photoelectric conversion, and photochemical conversion, among which solar photothermal conversion is currently the most popular form of utilizing solar energy in the world. The basic principle of solar photothermal conversion is to collect solar radiation energy by designing selective absorbing materials and their structures, and convert them into thermal energy through the interaction of light and matter for utilization. However, since solar energy is a low-quality energy source with low energy density, in order to obtain higher photothermal conversion efficiency, corresponding technologies and devices (such as solar collectors) must be used to collect solar e...
