NOVELTY - A solar concentrator device has an enclosure including at least one light-path altering component (10) located at the front side, a back panel (30) located at the back side, and at least one side panel (20) extending from at least one light-path altering component to the back panel. At least one photovoltaic cell (40) is set within the enclosure and on the back panel. A fan (50) is also set within the enclosure.    USE - Solar concentrator device for generating vortex gas circulation within enclosure by running fan while at least one photovoltaic cell generates electricity.    ADVANTAGE - Formation of vortex gas circulation is facilitated inside the enclosure of the solar concentrator device, which is bounded by at least one light-path altering component, sidewalls, and the back panel. Heat sink assembly is optionally provided within the enclosure so to enable Internal convention through the vortex gas circulation to transfer the heat generated at the photovoltaic cell to all surfaces of the solar concentrator device to facilitate radiative and/or convective cooling at the outside surfaces of the enclosure.Heat transferred to at least one side panel and at least one light-path altering component is dissipated by conduction to ambient air outside the enclosure, convection through the ambient air or radiation from the outer surfaces of at least one side panel and at least one light-path altering component. All surfaces of the enclosure constitute the outer boundaries of the solar concentrator device which dissipates heat in various modes including conduction, convection, and radiation so that solar concentrator device can effectively dissipate the heat effectively than the conventional solar concentrators that do not employ a fan or an internal vortex gas circulation pattern.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an operating method of solar concentrator device.
