Abstract

A high solar flux photovoltaic concentrator receiver is disclosed for the generation of high electrical power at high efficiency for public and private use. The invention uses a wraparound interconnect to allow direct bonding of concentrator solar cells to a heat sink with solder or conductive epoxy. This approach allows series or parallel interconnection between multiple cells and provides for high thermal conductance to improve cooling the solar cells. Cooling the solar cells under high concentration of solar energy increases their electrical efficiency. A highly conductive di-electric is utilized to insulate the cell backs from the metal heat sink. The invention minimizes obscuration losses, improves thermal conduction, reduces coefficient of thermal expansion stresses, and can be produced at reduced manufacturing costs.
