抄録

The silicon (Si)/silicon carbide (SiC) quantum dot superlattice solar cells (SiC-QDSL) with aluminum oxide (A12O3-QDSL) passivation approaches a high short-circuit current (Jsc) of 4.77 mA/cm2 under AMI.5 and one sun illumination due to the quantum enhancement on effective bandgap and minimum transition energy. This value matches well with experimental measurement of 4.75 mA/cm2. To further optimize the conversion efficiency through the geometry of Al2O3-QDSL, we introduce several parameters to define a complete QDSL configuration. A high conversion efficiency of 17.4% is optimized by using the QD geometry from experiment and applying hexagonal QDSL formation with an inter-dot spacing of 0.3 nm.
