Abstract
The fabrication of GaSb infrared-sensitive photovoltaic cells designed to boost the energy-conversion efficiency in tandem solar cell stacks is reported. Located behind GaAs solar-cells in 50× concentrated light configurations, these GaSb cells will boost the stack efficiency by 6.5 percentage points for space (AM0) and 7.0 percentage points for terrestrial (AM1.5D) applications. Assuming a GaAs cell efficiency of 26.7% (AM1.5D, 50×) as recently reported, the GaAs on GaSb stack efficiency will be 33.7%. Reduced series resistance in future GaSb cells will allow tandem-stack energy-conversion efficiencies over 35%.This publication has 6 references indexed in Scilit:
