A light-absorbing or light-emitting solar cell assembly comprises an electrical insulator disposed on an electrically conductive substrate and that is provided with a metallized surface and at least one solar cell connected to the electrically conductive substrate, wherein the solar cell includes refractive secondary optics and is disposed in a recess in the insulator. The solar cell is connected to the substrate by the side orientated towards the substrate via an electrically conductive connection and the recess is dimensioned such that an interspace is produced laterally between the solar cell and the electrical insulator, the interspace being filled with a coupling medium and the solar cell being connected to the metallized surface by at least one electrical contact.

Solar cell assembly and also solar cell arrangement

The present invention relates to a reflective and/or refractive secondary lens system for focusing sunlight onto semiconductor elements, the secondary lens system being characterized according to the invention by a projection which is disposed around the basic body forming the secondary lens system. Furthermore, the present invention relates to a semiconductor assembly which includes the secondary lens system according to the invention, and also to a method for the production of this semiconductor assembly. In particular, this semiconductor assembly represents a concentrating solar cell module.

Reflective secondary lens system and semiconductor assembly and also method for the production thereof

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.

Solar cell module and method for its production

The present invention relates to a photovoltaic module, comprising at least two component cell groups (SCA) which are connected to each other and disposed on an electrically insulating basic body, which groups comprise respectively one solar cell which is applied on a thermally and electrically conductive carrier and a bypass diode which is applied at a spacing thereto, and which are contacted with each other via an electrical conductor, the bypass diode having a polarity which is inverse to the solar cell and the solar cell and the bypass diode being applied on the conductive carrier via a conductive connecting layer.
