Abstract

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.

具有两个串联p – n结的LED的光伏特性

摘要

研究了由OSRAM GmbH生产的具有两个串联p – n结的结构的大功率IR发光二极管（LED）的光伏特性。确定了基于具有不同发射波长的LED的光伏转换器的操作光谱范围。结果表明，这些LED的光电转换效率在808 nm波长下达到超过30％的值。这些转换器的高（高达2.6 V）输出电压使其可用于通过光辐射直接馈入低功率电子设备。
