A 31%-efficient GaAs/silicon mechanically stacked, multijunction concentrator solar cell

Conference ·
OSTI ID:6816465

Development and demonstration of a GaAs/silicon mechanically stacked, multi-junction (MSMJ) solar concentrator cell with an efficiency in excess of 30% is reported. This is the highest efficiency ever reported for a solar cell and this is the first solar cell to ever achieve an efficiency in excess of 30%. Our preliminary analysis suggests that an efficiency approaching 35% is possible with GaAs-based MSMJ cells. (22 refs., 2 tabs.)
