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

Patent number: 7770164Abstract: Interactive software applications are upgraded at a remote service center. The software applications are used at customer locations. Each software application may rely upon customer specific data and customer protocols. Periodically, a revised version of a software application becomes available for use. The customer specific data and/or customer protocols that the previous version of the software application implemented at a customer location may be identified at the remote service center. Subsequently, the revised version of the software application may be modified at the remote service center using the customer specific data and/or customer protocols. The modified revised software application may be transferred to the customer location for installation. The customer specific data may pertain to user interface settings of the software application.Type: GrantFiled: May 31, 2005Date of Patent: August 3, 2010Assignee: Siemens AktiengesellschaftInventors: Horst Schuelein, Klaus Gartner, Gerhard Strobl

Patent number: 7696429Abstract: The invention relates to a solar cell which comprises photoactive semiconductor layers extending between the front and the back contact, and an integrated protective diode (bypass diode), said protective diode having a polarity opposite to that of the solar cell and is provided at its front with a p-conducting semiconductor layer, and the protective diode is connected to the front contact. The aim of the invention is to provide a highly stable protective diode and to prevent a migration of metal atoms. For this purpose, a tunnel diode (38) extends on the p-conducting semiconductor layer (36) of the protective diode (32), said tunnel diode being connected to the front contact (14) via an n+ layer.Type: GrantFiled: May 10, 2005Date of Patent: April 13, 2010Assignee: Azur Space Solar Power GmbHInventor: Gerhard Strobl

Publication number: 20010039082Abstract: The present invention relates to a solar cell (10) comprising a semiconductor body (12) having an n+p junction. In order that the solar cell exhibits a good EOL behavior, it is proposed that the solar cell (10) comprise first and second areas (28, 30, 32, 34, 48) having differing thicknesses (d1, d2), the first area (28, 30, 48) forming a support structure of the solar cell and the second area (32, 34) having a considerably lower thickness than the first area.Type: ApplicationFiled: April 4, 2001Publication date: November 8, 2001Inventors: Gerhard Strobl, Karlheinz Tentscher, Paul Uebele

Patent number: 4642414Abstract: The invention relates to a solar cell, wherein, in order to increase the efficiency, an amorphous or microcrystalline silicon layer is disposed on the side facing the incident light, thereby enabling the surface recombination speed to be reduced. In a preferred embodiment, this silicon layer is doped and is therefore additionally available for charge carrier transport. High doping effects are thus avoided in the thin surface zone of the semiconductor body.Type: GrantFiled: May 16, 1985Date of Patent: February 10, 1987Assignee: Telefunken Electronic GmbHInventors: Klaus-Dieter Rasch, Gerhard Strobl
