Patent number: 10333015Abstract: The present invention relates to a solar cell assembly, comprising a solar cell attached to a bonding pad and a cooling substrate and wherein the bonding pad and the cooling substrate are joined to each other in a planar and flush manner such that the bonding pad and the cooling substrate are connected to each other in the form of a solid state connection. The invention further relates to a solar cell assembly that includes a solar cell attached to a bonding pad and a cooling substrate and wherein the bonding pad is attached on a surface of the cooling substrate such that the bonding pad and the cooling substrate are connected to each other in the form of a solid state connection. Also, a method for manufacture of such solar cell assemblies is provided.Type: GrantFiled: February 22, 2011Date of Patent: June 25, 2019Assignee: Saint-Augustin Canada Electric Inc.Inventors: Martin Ziegler, Sascha Van Riesen

Publication number: 20180212562Abstract: An optical concentration system for a solar energy assembly, in particular, for a concentrator solar energy assembly, for concentrating incoming light onto a target area such as a solar cell in the solar energy assembly, includes a first optical element for collecting the incoming light and forming a light cone toward the target area, and a second optical element adjacent to the target area. In order to provide an optical concentration system for a solar energy assembly, which allows a high efficiency for light transmission and concentration and which is easy to manufacture, the first optical element is a multi-focal element and that the second optical element is adapted to reflect the light to at least one region of the target area that is outside the center of the target area.Type: ApplicationFiled: July 11, 2016Publication date: July 26, 2018Inventors: Sascha Van Riesen, Martin Neubauer, Andreas Gombert

Patent number: 7932462Abstract: The present invention relates to an arrangement having at least one solar cell, which is formed by a first sequence of differently doped layers (1, 2, 11, 12) on a substrate (6, 16), and at least one bypass diode, which is connected to the solar cell, particularly in a monolithic, series-connected solar module. The arrangement is characterized in that the bypass diode is formed by a second sequence of layers (4, 5, 13, 14), which is arranged between the substrate (6, 16) and the first layer sequence (1, 2, 11, 12). With the proposed arrangement monolithic, series-connected solar modules can be formed at a very low loss of active receiving surface, the solar cells of which are protected by bypass diodes.Type: GrantFiled: November 3, 2005Date of Patent: April 26, 2011Assignees: Fraunhofer-Gesellschaft zur Förderung der angewandten e.V., Albert-Ludwigs-Universtät, AZUR SPACE Solar Power GmbHInventors: Sascha Van Riesen, Rüdiger Löckenhoff, Gerhard Strobl, Ron Dietrich, Wolfgang Koestler
