Structure and design of concentrator solar cell assembly receiver substrate

摘要

A substrate has a top side and a bottom side. A solar cell is secured to the top side of the substrate and has an anode and a cathode. A heat transfer element is secured to the bottom side of the substrate. An anode pad is formed on the top side of the substrate and is coupled to the anode of the solar cell; similarly, a cathode pad is formed on the top side of the substrate and is coupled to the cathode of the solar cell. The substrate coefficient of thermal expansion and the solar cell coefficient of thermal expansion match within plus or minus ten parts per million per degree C.
