Photovoltaic laser power converters (PVLPCs) are the core element of power-by-light (PBL) systems, which are basically made up of a power laser, an optical fiber, and a PVLPC. PBL allows the safe transfer of power in situations where the direct use of electrical energy to power electronic equipment is either not possible or not recommendable.
Here we show laser power converters with organic photovoltaic cells with good performance for application in laser wireless power transfer. The laser selection strategy is established and the upper limit of efficiency is proposed.
Laser technology plays a key role in the economical industrial-scale production of high-quality solar cells. Fraunhofer ILT develops industrial laser processes and the requisite mechanical components for a cost-effective solar cell manufacturing process with high process efficiencies.
The laser selection strategy is established and the upper limit of efficiency is proposed. The organic laser power converters exhibit a 36.2% efficiency at a 660 nm laser with a photon flux of 9.5 mW cm −2 and achieve wireless micro power transfer with an output of 0.5 W on a 2 meter scale.
Optical power transfer, or power-by-light (PBL in the following), is an alternative technology, which provides a smart solution in these special situations. The reason why PBL systems ensure safety in these applications is the achievement of galvanic insulation in the “exclusion region.”
In a PVLPC the input and output power are normally a design requirement defined by the application. As compared with solar cells, for a set output power, the larger the PVLPC active area, the lower the input light power density or irradiance.
