摘要

By simultaneously considering the enhancement of quantum confinement on the effective bandgap and minimum transition energy, the silicon (Si)/ silicon carbide (SiC) quantum dot superlattice (SiC-QDSL) with aluminum oxide (Al2O3-QDSL) passivation layer shows the high short-circuit current (Jsc) of 4.77 mA/cm2 in theoretical, which agrees with the Jsc of 4.75 mA/cm2 obtained in the experiment under an AM1.5 and one sun illumination. Moreover, the reduction of efficiency in an ultra-dense QD configuration can be ameliorated by exploiting the Al2O3 passivation layer. As the result, a high conversion efficiency of 16.3% is optimized by using the QD geometry from experiment and an inter-dot spacing of 0.3 nm.
