[0049] Anti-reflection coating

[0050] 500 g of a silica gel solution was prepared by mixing TEOS and an aqueous hydrochloric acid solution with a pH of 2 at a weight ratio of 1:1.5. An aqueous hydrochloric acid solution with a pH of 2 was further added to dilute to 2000 g. The resulting solution was deposited on a glass substrate with a spin coater at a speed of 1000 rpm. The coating was dried at 100° C. for 10 minutes to form a lower layer with a coating thickness of 50 nm.

[0051] 500 g of a silica gel solution was prepared by mixing TEOS and an aqueous hydrochloric acid solution with a pH of 2 at a weight ratio of 1:1.5. An aqueous hydrochloric acid solution with a pH of 2 was further added to dilute to 1850 g. 100 g of PMMA beads with a particle size of 50 nm were added to the solution, followed by 50 g of silica particles with a particle size of 100 nm. The resulting suspension was deposited on the lower layer using a spin coater at a speed of 1000 rpm. The coated...

Abstract

The invention relates to an optical component with a stain resistant layer, and a preparation method and application thereof. The optical component of the present invention comprises: a substrate; anantireflection layer over the substrate; and a stain resistant layer over the antireflective layer, wherein the stain resistant layer comprises inorganic oxide particles and an inorganic oxide matrix,at least a portion of the volume of at least a portion of the inorganic oxide particles extending beyond the surface of the inorganic oxide matrix. The optical component of the invention has stain resistance and can maintain the stain resistance for a long time. The optical component of the present invention will permanently improve the power output of a photovoltaic assembly when used in a photovoltaic module.

Description

technical field [0001] The present invention generally relates to optical components with stain-resistant layers and photovoltaic components using the same. Specifically, the present invention relates to an optical component comprising a substrate, an antireflection layer and a stain-resistant layer, wherein the stain-resistant layer comprises inorganic oxide particles and an inorganic oxide matrix, at least a portion of the volume of at least a portion of the inorganic oxide particles The extension protrudes beyond the surface of the inorganic oxide matrix. The stain-resistant layer of the present invention has excellent durability. The invention also relates to the preparation method of the optical component and its application in photovoltaic components. Background technique [0002] In a conventional configuration, a photovoltaic module includes a photovoltaic cell, an encapsulant on both sides of the photovoltaic cell, and two panels on opposite front and rear sides o...
