6 FAQs about [Making photovoltaic panels requires lasers]

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.

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.

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.

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.

Can laser annealing be used for silicon photovoltaic devices?

Sun and Gupta (Sun and Gupta 2018a) reported the application of laser annealing for silicon photovoltaic devices. They showed that below the laser melting threshold fluence, the electrical properties were not degraded. Above the laser ablation threshold, significantly higher dislocation density was observed.

What are the applications of high-power laser processing for photovoltaic devices?

The various applications of high-power laser processing for photovoltaic devices have been discussed, but lasers also play an important role in medical device manufacturing for cutting, marking, and drilling applications.
