摘要： Various embodiments provide improved devices for solar electric and thermal energy conversion by including a reflector. The various embodiments may include solar electric conversion elements, solar thermal conversion elements, or both. The reflector may increase total energy output of a solar energy conversion device by concentrating solar radiation on a radiation absorber coupled with one or more conversion elements. Also, the reflector may prevent losses from gaps that would otherwise be present between solar energy conversion devices. In different embodiments, the reflector may be asymmetric or symmetric. Further, the reflector may be optimized in dimension and arrangement for a particular location. Optimization may be for year round performance and thereby avoid the need to shift the reflector or conversion device with the changing seasons.

摘要： Various embodiments provide devices for more efficient thermoelectric conversion by including a getter within a solar energy generation module. Solar energy generation modules may function in the vacuum of an evacuated enclosure to promote efficiency. A getter may improve the quality of the vacuum and thereby improve the efficiency of the solar energy generation module. A getter is more effective at improving vacuums if the getter is heated. Therefore, in various embodiments the getter may be thermally coupled with a heat absorber.
