Abstract
A wear-resistant self-cleaning solar cell panel includes a transparent substrate. A plurality of continuous microstructures are arranged on the transparent substrate, and each microstructure is an inverted pyramid or an inverted conical hole, and the microstructure is filled with a plurality of superhydrophobic nanomaterials, the microstructures and the superhydrophobic nanomaterials jointly constitute a composite surface of the solar cell panel. An angle of a side wall of the inverted pyramid or the inverted conical hole is α, wherein 30°<α<90°. A side length of the microstructure is a, wherein 1 μm<a<2 mm. A spacing between adjacent microstructures is b, wherein 10 nm<b<2 mm. The superhydrophobic nanomaterials are filled into the microstructure by an in-situ deposition method or an indirect filling method.
