Abstract: A pre-formed solar panel (1) to be mounted on a support plane (SP) is disclosed. In a direction from a first end (E1) to a second opposing end (E2), the panel has at least a first planar section (S1), a plastically deformed section (P) and a second planar section (S2), wherein the plastically deformed section maintains the first and the second planar section relative to each other at an enclosed angle (A1) in a range between 30° and 170°, and wherein an area of at least one of the planar sections is provided with a photovoltaic layer (3).

Abstract: The invention relates to a photovoltaic cell, comprising a plate shaped substrate of a semiconductor material with a solar face and a connection face, a first volume of the substrate adjacent to the solar face is doped with a first polarity, the second volume is doped with a second polarity and the volumes are separated by a pn-junction, a number of apertures in the substrate extending between both faces and in which a plug has been positioned of which a part is conducting, contact tracks at the solar face of the substrate connected with the first volume and the conducting part of the plug, first contacts at the connection face of the substrate connected with the conducting part of the plug and second contacts located at the connection face of the substrate connected with the second volume, wherein the specific electrical conductivity of the plug decreases from its centre to the contact face with the substrate.

Abstract: A photovoltaic device, having an improved passivation of surfaces, such as a circumferential outer wall and/or an aperture wall of a back contact metal wrap-through photovoltaic device, for example, into which the pn-junction of first and second semiconductor layers extends. The passivation comprises a passivating layer of a first type, covering at least part of such wall substantially comprised by the depletion region across the pn-junction; a passivating layer of a second type, covering at least part of such wall comprised by the first semiconductor layer, and a passivating layer of a third type covering at least part of the outer wall comprised by the second semiconductor layer.
