Chin-Chia Hsu Broadband Quantum Dot-in-a-Well Solar Cells

By stacking InxGa1-xAs quantum dot-in-a-well (DWell) layers of different compositions, we can increase the broadband absorption range near photon energy = 1eV for the solar cells. We add dopants in the In0.1Ga0.9As quantum wells to investigate the photovoltaic performance for the solar cells. Open-circuit voltage (VOC) is increased to 0.74 V by P-type doping. However, the dopings decrease the short-circuit current density. Under concentrated sunlight, Voc is increased with the number of suns, and the N-type doped Dwell solar cell shows a best efficiency to 9.6%.
