Photocurrent of DWELL and GaAs control cell of different sizes (, , and ) under AM 1.5 global illumination. The inserted picture is the schematic diagram of the DWELL solar cell with six-stacks of InAs QDs embedded in InGaAs quantum wells.
A comparison of the dark behavior of GaAs control and DWELL cells for the same dimensions (, , and ). (a) Measured and simulated local ideality factor for the control cells, (b) Measured and simulated semi-logarithmic dark current density for the control cells, (c) Tested local ideality factor, and (d) Dark current density for DWELL cells. The simulation is based on Eq. (3), where the parameters extracted by curve fitting are illustrated in Table II.
Measured short circuit current densities , open circuit voltages , and efficiencies of the GaAs control cells and InAs DWELL solar cells under AM 1.5 G illumination.
Parameters used in curve-fitting control samples using SRH statistics.
