Intrinsic losses in photovoltaic laser power converters
Applied Physics Letters, 2021Using photovoltaic cells as photovoltaic laser power converters (PLPCs) is a potential technology for long-range wireless power transfer. Intrinsic processes that limit the performance of PLPCs have not been fully investigated. Based on a thermodynamic model, we categorize and calculate the intrinsic losses in PLPCs.

Laser Power Converters for optical power supply
Proceedings of the 2011 34th International Spring Seminar on Electronics Technology (ISSE), 2011Laser Power Converters are dedicated semiconductor devices that convert optical energy into electrical energy. Opposed to solar cells they are optimised for high energy density and conversion efficiency mostly under laser illumination. These cells are applied as power supply in electromagnetically sensitive areas or for galvanic decoupling of ...

GaAs converter for high power laser diode
Conference Record of the Twenty Fifth IEEE Photovoltaic Specialists Conference - 1996, 1996Transmission of electrical power in an optical form is of increasing interest. Many applications of this technique can have high conversion efficiency over 50%. An optical power transmission system consists of a laser (acting as a power source) and a photovoltaic device, eventually coupled by an optical fiber used as a waveguide.

High-Voltage GaAs Photovoltaic Laser Power Converters
IEEE Transactions on Electron Devices, 2009The main drawback of photovoltaic (PV) laser power converters based on GaAs material is the low output voltage, which is often insufficient to power electronic circuits directly. Aside from the use of a dc-dc converter in combination with a single PV converter, it is possible to boost the voltage by the monolithic serial interconnection of several ...
