A system for enhancing overall energy production of CSPs through amplification of solar heat collection. In one embodiment, the system comprises a linear solar-thermal concentrator for concentrating solar light comprising a curved surface, two side walls, and an opening; a fluid conduit disposed within the linear solar-thermal concentrator that carries a working fluid through the linear solar-thermal concentrator; and a convection cover disposed over the opening of the linear thermal concentrator that traps heat convection energy within the linear solar-thermal concentrator.
