20150325711 | SEMICONDUCTOR COMPONENT HAVING HARDNESS BUFFER AND USE THEREOF - The invention relates to a semiconductor component that has an improved hardness buffer compared to the prior art. Lower penetrating dislocation densities are achieved thereby, especially for buffer layers having an increasing lattice constant. The semiconductor component according to the invention can be a solar cell. In this case a substantially higher efficiency of the solar cell is observed compared to conventional solar cells, thanks to the improved hardness buffer. The invention further relates to the use of the semiconductor component according to the invention or of the multiple solar cell according to the invention for energy generation in satellites in space or in terrestrial photovoltaic concentrator systems. | 11-12-2015 |

20150372179 | MULTI-JUNCTION SOLAR CELL, METHODS FOR THE PRODUCTION THEREOF, AND USES THEREOF - A multi-junction solar cell having at least three p-n junctions is proposed, which comprises a rear-side subcell comprising GaSb, which has at least one p-n junction, and a front-side subcell which has at least two p-n junctions and which is characterised in that the rear-side subcell has a ≧2%, in particular >4%, larger lattice constant than the front-side subcell and the two subcells are connected to each other via an optically transparent and electrically conductive wafer-bond connection. The multi-junction solar cell achieves a high absorption up to the band gap energy of the lowermost GaSb-comprising subcell and a photoelectric voltage which is increased relative to multi-junction solar cells from the state of the art. Furthermore, methods for the production of the multi-junction solar cell according to the invention are presented and uses of the multi-junction solar cell according to the invention are indicated. | 12-24-2015 |
