20080230109 | Solar Cell Module and Method For Its Production - A solar cell module and a method for the production thereof, are used in particular in the field of concentrating solar technology. The solar cell module has a large number of two-dimensionally disposed solar cells. These solar cells are applied on a substrate which is coated with a metal layer on the surface orientated towards the solar cells. The metal layer is thereby structured in such a manner that it is subdivided into individual two-dimensional portions which are assigned respectively to one solar cell. The metal layer in each of the portions has two regions which are electrically insulated from each other, the first region extending under the assigned solar cell and contacting the latter in an electrically conductive manner. The second region is likewise connected to the other electrical contact of the solar cell. In order to produce a parallel and series circuit of the individual solar cells, the individual portions of the metal layer are now connected to each other in a suitable manner by means of connecting portions which, for their part, are part of the metal layer. | 09-25-2008 |

20100193002 | SEMICONDUCTOR COMPONENT, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF - The invention relates to a semiconductor component which contains one semiconductor layer containing germanium. On the rear-side, i.e. on the side orientated away from the incident light, the semiconductor layer has at least one layer containing silicon carbide which serves, on the one hand, for the reflection of radiation and also as rear-side passivation or as diffusion barrier. A method for the production of semiconductor components of this type is likewise described. The semiconductor components according to the invention are used in particular as thermophotovoltaic cells or multiple solar cells based on germanium. | 08-05-2010 |
