Research progress of antireflection coatings with porous structure prepared by sol gel method
Porous structure anti reflection film has good anti reflection performance and is widely used in the photo-voltaic industry.The preparation methods of antireflection coatings mainly include sol gel method,etching method,self-assembly method,vapor deposition method and anodic oxidation method.Because the sol gel method has the advantages of simple preparation process,low production cost,and diversified sources of raw materials,this paper summarizes the research status of the preparation of porous antireflection coatings by the sol gel method,with a view to providing reference for research in related fields.
