Temperature Dependence of Dark Current Properties of InGaAs/GaAs Quantum Dot Solar Cells

Lu, Hao Feng; Fu, Lan; Jolley, Greg; Rao Tatavarti, Sudersena; Jagadish, Chennupati; Tan, Hark Hoe


Performances of GaAs reference solar cells and 10-layer InGaAs/ GaAs quantum dot solar cells were tested using AM1.5 illumination with results indicate that quantum dot (QD) structures improve the photo-current density compared to reference devices. Systematic measurements of the dark current versus voltage (I-V) characteristics were also carried out as a function of temperatures from 30K to 310K. The QD solar cell (QDSC) displays a more rapid change of dark current with increasing temperature...[Show more]
