Abstract
The electroluminescence and photoluminescence from an InAs/GaAs1-xSbx quantum dot solar cell are investigated as a function of temperature and correlated to the PV characteristics of the cell over the same temperature range. Analysis of the dominant recombination mechanism is shown to change from radiative to non-radiative above ~ 150 K, which is consistent with a reduction in the Jsc (and Voc) at evaluated temperatures in these devices.
