Systems and methods in accordance with various embodiments of the invention provide a photovoltaic concentrator tile for a space-based solar power (SBSP) system including constituent components thereof. In a number of embodiments, the photovoltaic concentrator tile include a one photovoltaic cell, a reflector, a power transmitter and circuitry configured to perform a variety of control functions. Embodiments also provide compactible structures, materials for improving thermal emissivity, and methods and mechanisms for manufacturing and using these components.

Ultralight photovoltaic power generation tiles

A space-based solar power station, a power generating satellite module and/or a method for collecting solar radiation and transmitting power generated using electrical current produced therefrom is provided. Each solar power station includes a plurality of satellite modules. The plurality of satellite modules each include a plurality of modular power generation tiles including a photovoltaic solar radiation collector, a power transmitter and associated control electronics. Numerous embodiments relate to efficient power generation tiles. In one embodiment, an efficient power generation tile includes: at least one photovoltaic material; and at least one concentrator that redirects incident solar radiation towards a photovoltaic material such that the photovoltaic material experiences a greater solar flux relative to the case where the photovoltaic material experiences unaltered solar radiation.

Compactable power generation arrays are provided. The compactable power generation arrays may include a structural substrate body having an array of solar concentrators configured to receive and re-direct solar radiation onto a plurality of photovoltaic (PV) cells. In many other embodiments the PV cells may be disposed upon a back surface of each of the solar concentrators such that an adjacent solar concentrator is configured to re-direct solar radiation onto the PV cell disposed on the back surface of the adjacent solar concentrator.

Compactable power generation arrays

A space-based solar power station, a power generating satellite module and/or a method for collecting solar radiation and transmitting power generated using electrical current produced therefrom is provided. Each solar power station includes a plurality of satellite modules. The plurality of satellite modules each include a plurality of modular power generation tiles including a photovoltaic solar radiation collector, a power transmitter and associated control electronics. The power transmitters can be coordinated as a phased array and the power generated by the phased array is transmitted to one or more power receivers to achieve remote wireless power generation and delivery. Each satellite module may be formed of a compactable structure capable of reducing the payload area required to deliver the satellite module to an orbital formation within the space-based solar power station.

Large-scale space-based solar power station: multi-scale modular space power

A virtual substrate includes a handle support and a strain-relieved single crystalline layer on the handle support. A method of making the virtual substrate includes growing a coherently-strained single crystalline layer on an initial growth substrate, removing the initial growth substrate to relieve the strain on the single crystalline layer, and applying the strain-relieved single crystalline layer on a handle support.
