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. | |
