    Abstract: 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.

    Abstract: 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.
