Photovoltaic laser power converters for wireless optical power supply of sensor systems

2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE), 2016
Optical power transmission (also called power-by-light) is an elegant solution to power wireless sensor nodes. At the sensor, optical power in form of monochromatic laser light is converted to electricity by photovoltaic laser power converters. These photovoltaic cells are optimized for the monochromatic wavelength of the light — opposed to solar cells,

Efficiency limits of laser power converters for optical power transfer applications

Journal of Physics D: Applied Physics, 2013
We have developed III-V-based high-efficiency laser power converters (LPCs), optimized specifically for converting monochromatic laser radiation at the eye-safe wavelength of 1.55 m into electrical power. The applications of these photovoltaic cells include high-efficiency space-based and terrestrial laser power transfer and subsequent conversion to ...

On the fundamental efficiency limits of photovoltaic converters for optical power transfer applications

2013 IEEE 39th Photovoltaic Specialists Conference (PVSC), 2013
Dedicated photovoltaic converters for the conversion of monochromatic laser radiation (laser power converters (LPCs)) have been developed for high efficiency conversion of laser radiation at 1550 nm into electrical power. The LPC design is based on the InGaAsP/InP material system and achieves a maximum conversion efficiency of 45 % (±1%) under 1.55 μm ...
