Photovoltaic Panel Laser System

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.

What is a 20 kW solar panel laser?

The laser is a CW high-energy Yb-doped fiber laser emitting at a center wavelength of 1075 nm with ∼1 m 2 of effective beam area. For 20 kW illumination of a solar panel having 0.6 m 2 of area, optical simulations and thermal simulations indicate an electrical output power of 3000 W at a panel temperature of 550 K.

Will a 905 nm laser-beam illuminate a solar panel?

In other words, our diode-laser simulations predict that when the 905 nm laser-beam illuminates the above-described solar panel, the resulting electric power outputs will be quite comparable to those for the Yb-fiber laser case.

Does a solar-pumped laser need a lens or solar tracking?

A solar-pumped laser (SPL) that converts sunlight directly into a coherent and intense laser beam generally requires a large concentrating lens and precise solar tracking, thereby limiting its potential utility. Here, we demonstrate a fully-planar SPL without a lens or solar tracking.

What is the difference between a pvlpc and a solar cell?

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.

Are solar-powered lasers a good idea?

A solar-powered laser enjoys far greater system simplicity, and benefits from a nearly eternal and free pump source. Overall, this study lights a way to take solar-powered lasers to new heights, with a clear blueprint for high-efficiency, space-ready solar lasers.
