Abstract (en)
[origin: EP2166577A1] A solar cell is provided with a down-converter that converts incoming high energy photons into two or lower energy photons before conversion to electric current, in order to provide for more efficient conversion. The down-converter comprises a combination of Neodymium and Ytterbium ions in a sulfide. The sulfide may ne Indium Sulfide, doped with the Neodymium and Ytterbium. The indium sulfide may be combined with a CIS (Copper Indium Sulfide layer to form active layers of a solar cell, or the sulfide with Neodymium and Ytterbium may be used as a separate filter before conversion to electric current. A solar cell may be provided with an up converter realized by means of quantum dots in an absorber matrix.
