A convective method is employed to cool a solar concentrator device. The convective method employs formation of a vortex gas circulation inside an enclosure of the solar concentrator device, which is bounded by at least one light-path altering component, sidewalls, and a back panel. Optionally, a heat sink assembly can be provided within the enclosure. Internal convention through the vortex gas circulation transfers the heat generated at a photovoltaic cell to all surfaces of the solar concentrator device to facilitate radiative and/or convective cooling at the outside surfaces of the enclosure.
