Abstract:
We consider a high-efficiency photovoltaic module optimized for conversion of monochromatic radiation with a wavelength of 809–850 nm. The module includes four photovoltaic converters with a total area of 16 cm$^2$, which operate with laser radiation of a power higher than 1 W and ensure a working voltage higher than 4 V. In the development and obtaining AlGaAs/GaAs structures for receiver-converters of radiation, we have used the method of epitaxy from the liquid phase and the method of metalorganic vapour-phase epitaxy. When the photovoltaic module operates in the regime of uniform irradiation of the light-detecting surface, the efficiency of conversion of a high-power (6.2 W) laser radiation exceeds 60%.
Keywords:
photovoltaic converter, laser radiation, AlGaAs/GaAs, module, epitaxy.
