Use laser pointer to illuminate photovoltaic panels

What is a photovoltaic laser power converter (pvlpc)?

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.

Can a laser beam illuminate a solar cell?

Laser beaming holds the promise of effectively implementing this paradigm. With this perspective, this work evaluates the optical-to-electrical power conversion that is created when a collimated laser beam illuminates a silicon photovoltaic solar cell that is located kilometers away from the laser.

Why is laser technology important for solar energy production?

Solar energy is indispensable to tomorrow´s energy mix. To ensure photovoltaic systems are able to compete with conventional fossil fuels, production costs of PV modules must be reduced and the efficiency of solar cells increased. laser technology plays a key role in the economical industrial-scale production of high-quality solar cells.

How much power does a laser panel produce?

Our results also predict about 15% OE conversion in the laser power range of 10–20 kW, with panel temperature in the 436–560 K range—in particular, an electrical output of 3000 W from a 0.6 m 2 panel illuminated by 20 kW 1075-nm beam, where the panel operates at a temperature of 550 K.
