NOVELTY - The solar cell (1000) has a concentrator that concentrates an incident radiant energy into a concentrated radiant energy. A refraction element receives the concentrated radiant energy and splits radiant energy into several bands of radiant energy. Each band of several bands has a frequency range and impinges on an area (1310). Several band solar cells are arranged to receive one of several bands that impinges on an area and also tuned to absorb the frequency range of the one of several bands.    USE - High efficiency solar cell for creating current from incident radiant energy.    ADVANTAGE - The cost-effective electric energy creation device is provided with the ability to more efficiently convert light energy into electricity. The device for creating electricity from light requires less light for the same amount of electricity and converts a greater percentage of a light emission spectrum into electricity. Since the carriers population of the solar cell is inevitably increased, the collection efficiency is also increased. The use of double or triple-layer solar cells with more than one material combination leads to higher efficiency solar cells. Since the transmission of radiant energy through the top cell is as critical as its absorption characteristics, the solar cell optimizes the layering of bulk materials for both absorption and transmission. By sacrificing some of the gains that can be obtained by increased absorption we can significantly reduce the losses due to thermal and stimulated recombination effects in upper layers. The solar cell is provided with no excess tunnel junctions that are needed to connect the top cell to the bottom cell. The bottom cell is a super lattice region, includes germanium layers that are tuned to absorb photons having energies near 1 eV. The solar cell is featured with high mobility of carriers in both the top cell and the bottom cell. The perfect lattice matching among the layers is realized, and high carrier transport is achieved.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the solar cell.
