Method for Forming a Nanostructured Thin Film with Porosity Gradient on an Array of Sloped Outdoor Panel Surfaces Using Meniscus Drag

摘要

A method of forming a thin film coating on sloped outdoor panel surfaces is disclosed. The method uses a thin-film coating applicator assembly for coating substrates in outdoor applications. The innovative method of forming a thin-film coating may be adapted to apply performance enhancement coatings on installed photovoltaic panels and glass windows in outdoor environments. The coating applicator is adapted to move along a solar panel or glass pane while applicator mechanisms deposit a uniform layer of liquid coating solution to the substrate's surface. The applicator assembly comprises a conveyance means disposed on a frame. Further disclosed are innovative applicator heads that comprise a deformable sponge-like core surrounded by a microporous layer. The structure, when in contact with a substrate surface, deposits a uniform layer of coating solution over a large surface.
