title = "Investigation of InAs/GaAs1-xSbx quantum dots for applications in intermediate band solar cells",
abstract = "The reduction of the effective band gap and the valence band offset are observed by increasing the Sb composition in GaAs1-xSbx matrix encapsulating InAs quantum dots (QDs). To investigate the potential of the InAs/GaAs1-xSbx system for intermediate band solar cells a p-i-n solar cell with a degenerate valence band is grown. An enhancement in the QDs region with increasing temperature is observed in temperature dependent external quantum efficiency measurements. An 's-shape' behavior of the short circuit current density, Jsc, is observed as the temperature increases. Ongoing investigations to illuminate the physical mechanisms contributing to the 's-shape' behavior of Jsc will also be presented.",
