Characterization of ultra high power laser beam PV converters

Abstract

Edge illuminated laser power PV converters of near-IR region (800-850nm) were made by liquid phase epitaxy. The developed converters are based on the GaAs active region with a wide (50-100 µm) AlGaAs waveguide layer. Gradient Al content in the waveguide layer ensured effective light collection on the p-n junction. Methods of device characterization based on high spatial resolution optical techniques were developed. Efficiency of 41.5% (no ARC applied) of laser power (850nm) conversion has been demonstrated at light power density of 8kW/cm2.
