摘要：
Photovoltaic characteristics of high-power IR light-emitting diodes (LEDs) manufactured by OSRAM GmbH on the basis of structures with two in-series p-n junctions have been studied. The spectral range of operation of photovoltaic converters based on LEDs with different emission wavelengths was determined. It was shown that the efficiency of photovoltaic conversion of these LEDs reaches values exceeding 30% at a wavelength of 808 nm. The high (up to 2.6 V) output voltage of these converters allows them to be used for direct feeding of low-power electronic devices by optical radiation.
