Solar cell for intermediate band coupling with quantum dots optimum light by diffraction, has cells, lower internal contact that is separated from semiconductor by layer of low refractive index

摘要

The solar cell has cells, lower internal contact that is separated from the semiconductor by a layer of low refractive index. A series of drills is provided in the front coated multiple anti-reflecting layers, which are part of diffraction structure. The drills are designed, so that in the diffraction range infrared sunlight incident in a light emanating cone.
