摘要： Embodiments of the present invention may utilize one or more techniques, alone or in combination, to maximize a surface area of a receiver that is configured to convert light into another form of energy. One technique enhances collection efficiency by controlling a size, shape, and/or position of a cell relative to an expected illumination profile under various conditions. Another technique positions non-active elements (such as electrical contacts and/or interconnects) on surfaces likely to be shaded from incident light by other elements of the receiver. Another technique utilizes embodiments of interconnect structures occupying a small footprint. According to certain embodiments, the receiver may be cooled by exposure to a fluid such as water or air.
