1. A low profile photovoltaic package, comprising
a circular base, comprising:
an upper layer comprising aluminum nitride, a middle layer comprising molybdenum, and a lower layer comprising oxygen-free, high-conductivity copper, wherein the upper layer, the middle layer, and the lower layer are characterized by a high and comparable coefficient of thermal expansion;the upper layer is electrically nonconductive;the middle layer and the lower layer are electrically conductive; andelectrically conductive traces on a top surface of the upper layer; an annular ceramic ring hermetically sealed to the top surface with an epoxy or with an adhesive, wherein the annular ceramic ring is configured to form a compartment; a photovoltaic device mounted to the circular base within the compartment and electrically interconnected to the electrically conductive traces; bypass diodes mounted to the circular base, wherein the bypass diodes are interconnected to the photovoltaic device and to the electrically conductive traces; an externally threaded pedestal fixedly attached to a bottom surface of the lower layer; a cover, wherein the cover comprises:
a quartz window comprising an outer diameter; andan iron-nickel-cobalt alloy disk characterized by a low thermal expansion coefficient and comprising an inner diameter.
