Abstract: The present disclosure provides a window for a building or structure. The window comprises first and second panels which have major surfaces and are at least largely transmissive for visible light. The second panel has major surfaces which are smaller than the major surfaces of the first panel. Further, the second panel is positioned parallel to the first panel such that the second panel is within a projection of the circumference of the first panel in a direction along the surface normal of the first panel. The first and second panels are laminated together. The first and second panels are arranged such that the first panel has a border region which extend beyond the circumference of the second panel and the laminated first and second panels can be supported at the border region of the first panel.

Abstract: The present disclosure provides a window unit for a building or structure. The window unit comprises a first panel having an area transmissive for at least a portion of visible light. The first panel has opposite major surfaces. The window unit also comprises a second panel having an area transmissive for at least a portion of visible light. The window unit further comprises a spacer spacing the first panel from the second panel. At least one electric or electronic element is positioned within the spacer and indirectly or directly electrically coupled to at least electric component positioned within the window unit.

Abstract: A window unit for a building or structure comprises a first panel and a second panel each having an area transparent for at least a portion of visible light and a spacer spacing the first panel from the second panel. The spacer surrounds a space between the first and second panels. A first edge area of the first panel extends beyond a projection of the circumference of the spacer in a direction of a surface normal of the first panel. The window unit also comprises a housing incorporating at least one electric or electronic element which is indirectly or directly electrically coupled to at least one other electrical component positioned within the window unit. The housing is positioned at or near the spacer and at least partially within a projection of the circumference of the first edge area of the first panel in the direction of the surface normal of the first panel.

Abstract: The present disclosure provides a window unit for a building or structure. The window unit is arranged for generating electricity and comprises a panel having an area that is transparent for at least a portion of visible light and having a light receiving surface for receiving light from a light incident direction. The window unit further comprises at least one series of solar cells, each solar cell being a bifacial solar cell and having opposite first and second surfaces each having an area in which light can be absorbed to generate electricity, the solar cells being positioned such that in use the first surfaces are oriented to receive light from the light incident direction and the second surfaces receive light from an opposite direction.
