The lower surface of the frame is provided with a heat preservation back plate. The upper surface of the frame is sequentially laminated with a glass cover plate, a first photovoltaic cell laminating adhesive, a photovoltaic cell slice, a second photovoltaic cell laminating adhesive, a transparent back plate, a third photovoltaic cell laminating adhesive and a heat absorbing component from top to bottom. A heat preservation cavity is formed between the heat preservation back plate and the heat absorption part.
摘要:
A method of manufacturing a transparent pane, in particular a glass pane, which includes on at least one of its main surfaces a surface structure including an assembly of specified individual motifs in relief, in particular pyramids, cones, or truncated cones, created by embossing or by rolling. A structure is created on the surface of the pane constituted by individual motifs, based on one or more basic motifs but which are distinguished from each other by their depth, their height, and/or the perimeter of their base area, and/or by the position of their peak with respect to their base. With this variation, formation of intensity peaks of the reflected light is prevented and at the same time a high quality of light trapping is obtained by panes suitable, for example, for solar applications.

Solar collector apparatus is described in which solar radiation is collected in a glazed cavity which may also include a transpired solar collector layer. Air warmed in the cavity may be used for space heating within buildings or diverted to heat management systems which facilitate, for example, heat storage. The glazing, particularly coated glazings, improve the performance of the devices by allowing solar energy to enter the cavity and preventing heat loss, and by negating the effect of ambient wind on the transpired solar collector layer.

A device and method of pre-attaching assemblies to glazing can provide for accurate fit or registration after installation. A solar panel provides power to an insulated glass unit. Mounting brackets are secured to the insulated glass unit. A plate adjustably attaches to the mounting brackets. After positioning the plate on the mounting brackets a solar panel is attached to the plate and the insulated glass unit is installed in a frame. The plate is adapted to be moved toward the frame such that the solar panel is flush to the frame after moving the plate. Trim pieces can then be installed over the portions of the plate not covered by the solar panel.
