International Classification:

G21K 1/00

US Classification:

250396 R, 427 58, 427122, 427123

Abstract:

An improved beam-defining aperture structure and method for fabrication is realized. An aperture opening is made in a thin conductive film positioned over a cavity in a support substrate, where the aperture size and shape is determined by the opening in the conductive film and not determined by the substrate.

Abstract:

A system is disclosed for providing electrical power responsive to solar energy. The system includes a Si cell, an AlGaAs cell, and a Ge cell. The Si cell is for providing electrical power responsive to solar energy within a first frequency range. The AlGaAs cell is coupled to a first side of the Si cell, and is for providing electrical power responsive to solar energy within a second frequency range. The Ge cell is coupled to a second side of the Si cell, and the Ge cell provides electrical power responsive to solar energy within a third frequency range.
