Strain-balanced type-II superlattices for efficient multi-junction solar cells

A. Gonzalo, A. D. Utrilla, D. F. Reyes +9

We propose type-II GaAsSb/GaAsN superlattices (SLs) lattice-matched to GaAs as a novel material for the 1 eV sub-cells present in highly efficient GaAs/Ge-based multi-junction sola…
