Abstract: In a method for producing a biocidal glass surface of a soda-lime glass, a glass surface of a soda-lime glass is indirectly or directly contacted with silver, silver salt, or silver ions and directly or indirectly heated using at least one laser beam of a laser such that an ion exchange of sodium ions from the soda-lime glass with silver ions of the silver ions or from the silver or the silver salt results and silver ions of the silver ions deposit in the region of the glass surface. Before being heated, the glass surface is coated with a transfer support including a layer of silver and a protective layer covering the silver layer, such that the protective layer directly contacts the glass surface, the glass surface then being heated using the laser. Also, a soda-lime glass having a biocidal glass surface is produced by the method.

Abstract: The invention relates to a photovoltaic insulating glazing comprising a multi-layer glazing with a photovoltaic module. The glazing is further characterized in that two contact strips for contacting the photovoltaic module are led out from an intermediate space between the glass layers and a spacer spaces the glass layers apart, thereby forming the intermediate space.

Abstract: The invention relates to a photovoltaic concentrator module with multifunction frame and also to a method for production thereof. The concentrator module has a lens—(1) and a base plate (2), between which a frame (3) extends. Between the lens plate (1) and the frame (3) and/or the base plate (2) and the frame (3), two sealing compounds (5) and/or adhesive compounds (4) extend, which compounds differ with respect to their hardening time and/or gas permeability.

Abstract: A transparent thermal insulation arrangement for heating buildings with solar energy includes a glass plate, and absorber and an edge bond between the glass plate and the absorber. The absorber has an absorber plate which is inherently rigid and is assembled with the glass plate by the edge bond. An intermediate space is formed between the glass plate and the absorber plate and is filled with an inert gas. In addition, a space is formed between the absorber plate and the wall of the building which may be filled with air.
