Coating structure applied to solar panels

Abstract

A coating structure for use in solar panels includes an optical coating having a plurality of low-refractive-index optical particles and a plurality of high-refractive-index optical particles. The low-refractive-index optical particles and the high-refractive-index optical particles are mixed, wherein the high-refractive-index optical particles and the low-refractive-index optical particles are distributed adjacent to each other in the optical coating, and the content of the low-refractive-index optical particles is not less than the content of the high-refractive-index optical particles. In this way, the optical coating reduces the refraction angle of light by combining the low-refractive-index optical particles and the high-refractive-index optical particles, thereby achieving the effect of effectively irradiating the solar panel module under different lighting conditions.
