Method for processing transparent cover plate and cover plate

Abstract

The invention relates to a method for processing a transparent cover plate (10) of a flat plate body (1), comprising: a) providing a transparent cover plate (10) having an outer side (27) to be directed towards the outside environment and an opposite inner side (28), the cover plate (10) comprising a structured region (15) with light scattering structures in at least one cover plate surface (11, 13) selected from the outer surface (11) and the inner surface (13) of the cover plate (10), or alternatively forming a structured region (15); b) forming at least one optical interference layer (16) on a portion of the cover plate side (27, 28) selected from the outer side (27) and the inner side (28), comprising: b1) applying a mask (24) to the cover plate (10), the mask (24) not covering a first region (22) of the cover plate surface (11, 13) of the cover plate side (27, 28) and instead covering a second region (23) of the cover plate surface (11, 13) of the cover plate side (27, 28) when viewed vertically through the cover plate (10), and the first region (22) and the second region (23) are arranged so as to overlap the structured region (15) still to be formed; b2) applying at least one optical interference layer (16) for reflecting light in a predetermined wavelength range onto a selected cover plate side (27, 28) of the cover plate (10), said optical interference layer (16) being applied to overlap with the mask (24) and with the first region (22) of the cover plate surface (11, 13) when viewed vertically through the cover plate (10); b3) removing the mask (24), wherein the optical interference layer (16) overlapping the mask (24) in vertical view is also removed.

Description

technical field [0001] The present invention belongs to the technical field of producing light absorbing panels, such as solar cell modules and solar collectors, as well as passive panels, which are intended to be used as integral parts of building envelopes or freestanding walls, and which fulfill architectural functions only. Background technique [0002] In everyday life, solar cell modules for generating photovoltaic energy from sunlight and solar collectors for converting sunlight into thermal energy are well known. Here and elsewhere, solar cell modules and solar collectors are collectively referred to as "light absorbing panels". Light absorbing plates are used to generate energy from sunlight or convert sunlight into heat. They are also called "active" slabs, in contrast to "passive" slabs, which are neither suitable nor intended for this purpose. [0003] The solar cell module includes a photosensitive semiconductor layer for converting sunlight directly into elec...
