Abstract :
The potential performance of GaAs-based mechanically stacked, multijunction (MSMJ) solar concentrator cells in 500X and 1000X concentrator modules is analyzed. A description of the concentrator module and the MSMJ concentrator cell is presented. A thermal analysis of the MSMJ cell assembly in the module is given, and implications of the module operating conditions for the design of the MSMJ cell are considered. The normal operating cell temperature of MSMJ cells in a concentrator module is higher than that of single-junction cells due to the stacked cell construction, which reduces the expected performance advantages of MSMJ versus single-junction cells
