Abstract: A solar concentrator module (80) employs a luminescent concentrator material (82) between photovoltaic cells (86) having their charge-carrier separation junctions (90) parallel to front surfaces (88) of photovoltaic material 84 of the photovoltaic cells (86). Intercell areas (78) covered by the luminescent concentrator material (82) occupy from 2 to 50% of the total surface area of the solar concentrator modules (80). The luminescent concentrator material (82) preferably employs quantum dot heterostructures, and the photovoltaic cells (86) preferably employ low-cost high-efficiency photovoltaic materials (84), such as silicon-based photovoltaic materials.
