<p>A high efficiency photovoltaic assembly, wherein a semiconductor solar cell array includes at least two semiconductor solar cells, each cell being characterized by a different incident light wavelength for optimal conversion efficiency of the cell, and means for directing an incident light beam toward the solar cells so that each cell receives the component of the incident light beam including its respective light wavelength for optimal conversion efficiency. The solar cell array may include a light wavelength analyzer such as a prism or diffraction grating for splitting the light beam into component rays of various wavelengths, which rays are then directed toward those solar cells which can optimally convert the respective wavelengths. The solar cell array could alternatively include a structure which directs the entire incident light beam serially through a succession of solar cells, wherein successive pairs of cells are arranged in a non-coplanar, spaced apart fashion.</p> |
