Abstract (en)
[origin: WO2014122308A1] The invention relates to a multi-junction solar cell having at least three p-n junctions, which contains a back-side sub-cell having at least one p-n junction and containing GaSb and a front-side sub-cell having at least two p-n junctions and which is characterised in that the back-side sub-cell has a lattice constant that is greater than the lattice constant of the front-side sub-cell by ≥ 2%, in particular by > 4%, and the two sub-cells are connected to one another by means of an optically transparent and electrically conductive wafer-bond connection. The multi-junction solar cell achieves high absorption up to the band gap energy of the bottommost sub-cell containing GaSb and a photovoltage that is increased in comparison with multi-junction solar cells of the prior art. The invention further relates to methods for producing the multi-junction solar cell according to the invention and uses of the multi-junction solar cell according to the invention.
