The benefits of advanced thermal packaging are demonstrated through a receiver package consisting of a monolithic interconnected module (MIM) which is directly attached to a high performance microchannel heat sink. Those packages can be applied in high-concentration photovoltaic systems and the generated heat can be used in addition to the electrical power output (CPVT systems). Thus, the total energy efficiency of the system increases significantly. A detailed exergy analysis of the receiver power output underscores the advantages of the new cooling approach.
