Abstract
The development and demonstration of the first solar cell to achieve an efficiency in excess of 30% are reported. The improved performance compared to previous GaAs/silicon mechanically stacked, multijunction (MSMJ) concentrator cells is due to improvements in the component cell technologies and to better optimization of the GaAs cell transmissivity. Preliminary analysis suggests that an efficiency approaching 35% is possible with GaAs-based MSMJ cells.
