Moreover, because silver nanoparticles are incorporated into the pores of the mesoporous silica, the silver nanoparticles are used stably and do not change color and odor. In addition, the spherical mesoporous silica exhibits various additional effects, including far-infrared ray emission and deodorization, attributable to silica.

Abstract: The present invention relates to a photovoltaic module characterized by comprising a heat radiating sheet overlaid with a ceramic coating layer, which is attached to a conventional photovoltaic module. In a method of increasing heat radiation with the aid of the ceramic coating layer provided on both sides or one side of the heat radiating sheet, heat generated by a solar cell due to the differences in thermal emissivity, thermal shear rate and surface area of a material is transferred to a solar EVA and then a heat radiating sheet thin plate that serves as a carrier, and returns back to the ceramic coating layer for emission. A high thermal emissivity is obtained by having a so-called heat transfer phenomenon in one direction, which resultantly improves a heat radiation performance and increases the refrigeration efficiency of the photovoltaic module and its peripheral devices to thus lower the internal temperature.
