Description
The non-uniform irradiance of fiber lasers influences the performance of power-by-light systems. We analyze the non-uniformity in both single and triple junction power converters in addition to other parameters that could reduce the efficiency such as manufacturing tolerances or series resistance effect. We present an experimental efficiency of 67.0 ± 0.9 % in triple junction power converters for an input power of 2.8 W using a laser wavelength of 857 nm. We demonstrate thus a high efficiency for non-uniformity irradiance.
