Multi-junction laser power converters exceeding 50% efficiency in the short wavelength infrared
Highlights Can achieve 53.6% efficiency with model-predicted 4-junction laser power converter Layer thicknesses can be extracted with one non-destructive measurement Can have higher efficiencies for laser power converters with larger bandgaps Designs optimized with luminescent coupling surpass absorption-matched designs
