6 FAQs about [Maximum power of photovoltaic solar laser]

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.

Which photovoltaic converter has the highest efficiency?

Recently, a PVLPC has demonstrated the highest efficiency for any photovoltaic converter, i.e., 68.9% at a laser illumination of 858 nm. This review begins with a brief overview of the functionalities of PBL systems and the critical requirements imposed to PVLPCs.

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.

What is the maximum conversion efficiency and PV body temperature?

FIG. 8. Maximum conversion efficiency and PV body temperature as a function of laser power, ranging from 100 to 50 000 W, for dSi = 180 and 500 μ m. In the simulations, the laser wavelength emission, the emission bandwidth, and the laser spot radius ( rsp) are 1075 nm, 10 nm, and 80 cm, respectively.

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.

Can a power-by-light system be used for photovoltaic (PV) cells?

However, researchers at Fraunhofer ISE are also working on another application for photovoltaic (PV) cells: Power-by-Light systems (also known as Power-over-Fiber) in which optical power transfer is used to supply electricity to electronics.
