Characterization of Below-Bandgap Absorption in Type II GaSb Quantum Dots in GaAs Solar Cells

An approach to derive the below-bandgap absorption in GaSb/GaAs self-assembled quantum dot devices using room-temperature external quantum efficiency measurement results is presented. Devices with five layers of delta-doped quantum dots placed in the intrinsic, n- and p-regions of a GaAs solar cell...
