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.
