Abstract: A solar cell module comprises an array of lenses, corresponding secondary optical elements and corresponding solar cell receivers. The solar cell receiver includes a solar cell having one or more III-V compound semiconductor layers, a diode coupled in parallel with the solar cell and connector for coupling to other solar cell receivers. The module includes a housing that supports the lenses such that each lens concentrates solar energy onto its respective solar cell.

Abstract: A method for assembling a concentrator photovoltaic solar cell array system for producing energy from the sun includes installing a foundation on a surface and coupling a central support to the foundation. A cross member is coupled to the central support and one or more inclined arms are coupled to the cross member and the central support. A support frame, which includes a first frame assembly arranged to couple to one or more solar cell subarrays, is coupled to the cross member. One or more solar cell subarrays are coupled to the first frame assembly thereby forming a solar cell array, wherein each solar cell subarray includes a plurality of triple junction III-V semiconductor compound solar cell receivers. To enable rotation of at least a portion of the central support coupled to the support frame, an actuator is installed.

Abstract: A concentrator photovoltaic solar cell array system includes a central support mountable on a surface and a solar cell array including triple junction III-V semiconductor compound solar cell receivers and a support frame coupled to the solar cell array and carried by, and rotatable with respect to, the central support about an axis orthogonal to the central longitudinal axis. The support frame can include (i) a first frame assembly coupled to the solar cell array and (ii) a second frame assembly coupled to the first frame assembly arranged to increase the rigidity thereof. The system also has an actuator for rotating the central support and the support frame as well as pivoting the support frame so as to adjust its angle with respect to the earth's surface, so that the solar cell array is maintained substantially orthogonal to the rays from the sun as the sun traverses the sky.

Abstract: A gas distribution injector for chemical vapor deposition reactors has precursor gas inlets disposed at spaced-apart locations on an inner surface facing downstream toward a substrate carrier, and has carrier openings disposed between the precursor gas inlets. One or more precursor gases are introduced through the precursor gas inlets, and a carrier gas substantially nonreactive with the precursor gases is introduced through the carrier gas openings. The carrier gas minimizes deposit formation on the injector. The carrier gas openings may be provided by a porous plate defining the surface or via carrier inlets interspersed between precursor inlets. The gas inlets may removable or coaxial.
