A monolithic multiple solar cell includes at least three partial cells, with a semiconductor mirror placed between two partial cells. The aim of the invention is to improve the radiation stability of said solar cell. For this purpose, the semiconductor mirror has a high degree of reflection in at least one part of a spectral absorption area of the partial cell which is arranged above the semiconductor mirror and a high degree of transmission within the spectral absorption range of the partial cell arranged below the semiconductor mirror.

Monolithic multiple solar cells

An adjustment-tolerant photovoltaic cell in which the front face has at least three sub-segments which can be directly struck by electromagnetic radiation is provided. At least two sub-segments are in the form of a first segment type, and at least one sub-segment is in the form of a second segment type. The sub-segments can be arranged such that at least two separate segment regions, which can be directly struck by the electromagnetic radiation, are formed for each of the first and the second segment types. At least two sub-segments of the first segment type can be connected to each other in parallel and/or are connected to each other via a transition region which ensures the lateral flow of current. Furthermore, the sub-segments of the first segment type can be connected in series to the at least one sub-segment of the second segment type.

Adjustment-tolerant photovoltaic cell

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 invention relates to a photovoltaic concentrator module with multifunction frame and also to a method for production thereof. The concentrator module has a lens- and a base plate, between which a frame extends. Between the lens plate and the frame and/or the base plate and the frame, two sealing compounds and/or adhesive compounds extend, which compounds differ with respect to their hardening time and/or gas permeability.

Photovoltaic concentrator module with multifunction frame

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.
