摘要：
Solar concentrator devices and techniques for the fabrication thereof are provided. In one aspect, a solar concentrator device is provided. The solar concentrator device comprises at least one solar converter cell; a heat sink; and a liquid metal between the solar converter cell and the heat sink, configured to thermally couple the solar converter cell and the heat sink during operation of the device. The solar converter cell can comprise a triple junction semiconductor solar converter cell fabricated on a germanium (Ge) substrate. The heat sink can comprise a vapor chamber heat sink. The liquid metal can comprise a gallium (Ga) alloy and have a thermal resistance of less than or equal to about five square millimeter degree Celsius per Watt (mm2° C./W).
