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.
摘要翻译：各种实施例通过包括反射器提供用于太阳能电和热能转换的改进的装置。各种实施例可以包括太阳能电转换元件，太阳能热转换元件或两者。反射器可以通过将太阳辐射集中在与一个或多个转换元件耦合的辐射吸收器上来增加太阳能转换装置的总能量输出。此外，反射器可以防止否则将在太阳能转换装置之间存在的间隙的损失。在不同的实施例中，反射器可以是不对称的或对称的。此外，反射器可以针对特定位置的尺寸和布置进行优化。优化可能是全年性能，从而避免了在不断变化的季节需要移动反射镜或转换装置。

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.
