Abstract: The present disclosure provides a device for window of a building or structure. The device comprises a panel having an area that is transparent for at least a portion of visible light and having opposite first and second major surfaces. The first major surface is a light receiving surface of the panel. The device further comprises at least one series of solar cells, each solar cell having a light receiving surface which faces the second major surface of the panel and is the directly or indirectly bonded to the panel at the second major surface in a manner such that light can be received by the light receiving surfaces of the solar cells without propagating through a gap between the panel and the light receiving surfaces of the solar cells. The at least one series of solar cells is positioned at and along an edge of the panel and between the edge and the area that is transparent for at least a portion of visible light.

Abstract: The present disclosure provides a device for generating electricity. The device comprises a panel having an area that is transparent for at least a portion of visible light and having a light receiving surface. The panel comprises at least one series of solar cells, each solar cell having opposite major surfaces having opposite electrical polarities, each solar cell overlapping another one of the solar cells and being electrically connected in series. The at least one series of solar cells is positioned along and in the proximity of an edge of the panel, along the area that is transparent for at least a portion of visible light and substantially parallel the light receiving surface of the panel.
