Embodiment Construction

[0041] Before delving into the detailed description, it should be noted that the drawings show components of a building-integrated photovoltaic device according to the present invention, some components (e.g., motor, converter) have been removed for the sake of clarity, since these components are outside the scope of those skilled in the art Anything known to the person is useless for understanding the invention itself and will only contribute to overall congestion of the drawings. Furthermore, especially in Figure 4A-Figure 4B to Figure 7 , the drawings are intended to be schematic as they do not reflect exact scale in order to better illustrate the underlying structure of the layers.

[0042] With reference to the cited figures, a building-integrated photovoltaic device, generally designated by reference number 1, is adapted and configured to close an opening (usually a window) on the facade of a building and to be illuminated by solar radiation passing through the openin...

Abstract

An integrated building photovoltaic apparatus (1), is suitable for closing an opening on a facade of a building and generating electricity from a solar radiation which pass through the opening. The particularity of the invention resides in that each photovoltaic slat (31) comprises a photovoltaic sheet (131) comprising interconnection grooves (51, 52, 53) which define in the photovoltaic sheet (131) a plurality of thin film solar cells (40, 40') monolithically connected each other in series, the plurality of thin film solar cells (40, 40') comprise at least two coupling thin film solar cells (40'), and each one of thin film solar cell comprises a through hole (39) and a close-pattern isolation groove (61) surrounding the through hole (39) so as to define an inactive area of the coupling single thin film solar cell (40') surrounding the through hole (39); the connection elements (12a, 12b) comprising first connection elements (12a) passing through the through holes (39). The present invention relates also to a method for making the photovoltaic slat (31) for the integrated building photovoltaic apparatus (1).

Description

technical field [0001] The present invention relates to a building-integrated photovoltaic (BIPV) device, and more precisely to a device adapted to close an opening in a building facade and to generate electricity from solar radiation passing through the opening, for example known as Building-Integrated Photovoltaic (BIPV) installations of "Photovoltaic Shutters". Background technique [0002] The expression "building integrated photovoltaics (BIPV)" generally refers to photovoltaic materials used to replace conventional building materials in parts of a building envelope, such as roofs, skylights or facades. It is increasingly incorporated into the construction of new buildings as a primary or auxiliary power source, although existing buildings can be retrofitted with similar technology. [0003] In particular, the devices mentioned are devices that can replace traditional windows (or glass or skylights, etc.) and traditional shutters (eg venetian blinds). [0004] Over ti...
