Abstract: In a solar battery cell, a plurality of silver electrodes are formed in a dot shape with a predetermined gap therebetween linearly along a rear surface tab line. Pitches among the silver electrodes are set so as to be large in a central part of a silicon substrate and small at the ends of the silicon substrate. By arranging many silver electrodes at ends of the silicon substrate having a large stress, the rigidity at the ends is improved, and the warpage is decreased, thereby suppressing cell cracking.

Abstract: 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.
