Abstract: The degradation of microwave module parameters of series-connected $p$–$i$–$n$ AlGaAs/GaAs photovoltaic converters under thermocycling in the temperature range of 25–80$^\circ$C and continuous laser radiation from multimode optical fibers with a total power of 2 W at a wavelength of 810 nm has been investigated. During thermocycling, stabilization of the photovoltaic parameters of the microwave module was observed with a decrease in the output electrical power from 955 mW to 926 mW and a decrease in efficiency by 3%.

Keywords: $p$–$i$–$n$ AlGaAs/GaAs photovoltaic converter, microwave module, multimode optical fiber, thermal cycling, electrical power, efficiency.
