Photovoltaic panel laser cutting light wavelength

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.

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.

Which laser wavelengths affect electrical contact properties?

Sánchez-Aniorte et al. studied the effect of three different laser wavelengths, 1064 nm, 532 nm, and 355 nm, on the electrical contact properties (Sánchez-Aniorte et al. 2012 ). The best results were obtained using green (532 nm) and UV (355 nm) lasers with excellent values for contact resistivity far below 1 mΩcm 2.

Can laser processing systems be used for photovoltaic applications?

The laser processing systems for photovoltaic applications have advanced such that commercial systems are available. These commercial systems can provide multifunctional capabilities such that ohmic contact formation, dopant activation, and other steps that can be carried out using the same machine.

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.

What is the wavelength emission of a laser?

(a) Laser power 10 000 W and dSi = 180 μ m and (b) laser power 10 000 W and dSi = 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. Using Eqs.
