Thermalization losses in Laser Power Converters for the first transmission window occur due to the energy difference between 808 nm wavelength photons and the GaAs bandgap energy which results in lower efficiency. In this work, we analyze the potential of increasing the bandgap using AlGaAs to minimize the energy difference. The optimum aluminum content is 7 % in both single and triple junction converters reaching a maximum ideal efficiency of 71% at 1 W/cm2 and 77% at 50 W/cm2.
