Abstract
Concentrated sunlight impinges on a large area photovoltaic device which is bonded to a highly pliable and thermally and electrically conductive structured copper strain relieving member; the lower face of the structured copper is sealed to a fluid cooled metal heat sink. Large power densities of sunlight are absorbed without appreciable temperature rise. The structured copper accommodates to the difference in expansion between the metal heat sink and the semiconductor wafer. Three embodiments utilize a single planar junction diode, an interdigitated diode, and series connected isolated junction diodes.
