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.

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 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.

Do solar panels work in direct sunlight?

These SPLs only work in direct sunlight, too, which calls for a solution that can thrive in “diffuse” sunlight—a much more common atmospheric condition. Their design is what’s called a “flat panel” SPL design, meaning it can be installed much in the same way a traditional photovoltaic solar panel can.

What is a solar pumped laser?

Solar-pumped lasers (SPLs), which convert sunlight into laser radiation, are of interest for applications, such as solar hydrogen generation, remote area telecommunications, space propulsion, space solar power systems, and high-efficiency photovoltaic energy conversion 1, 2, 3, 4, 5, 6, 7, 8.
