6 FAQs about [Laser welding of photovoltaic brackets]

How is laser welding used for metallization and interconnection of solar cells?

Laser welding is used for the metallization and interconnection of solar cells. Figure 21 (Schulte-Huxel et al. 2016) shows the interconnection of two cells using laser welding of Al foil. A glass plate is mounted on top of the foil to keep the aluminum foil flat during the laser welding process, and the laser beam is passed through the plate.

How a solar cell is laser welded?

A glass plate is mounted on top of the foil to keep the aluminum foil flat during the laser welding process, and the laser beam is passed through the plate. The solar cell interconnection is achieved by the Al foil contacting the rear side which is laser welded to the Ag screen-printed front side metallization of the next cell.

Can laser processing be used for perovskite solar cells?

Another application of laser processing for perovskite solar cells was demonstrated by Wilkes et al. in 2018. In perovskite solar cells, the electron transporting layer, most commonly TiO 2, requires high temperature (>450 °C) annealing, making it undesirable for the use of flexible plastic substrates.

Are nanosecond lasers suitable for bifacial PERC solar cells?

Both nanosecond and ultrafast lasers have been shown to be suitable for the opening in the dielectric layer. Based on cost considerations, nanosecond lasers could be very attractive for this application. Bifacial mono-PERC solar modules with a record efficiency of 24.06% have been reported (LONGi Solar 2019 ). PERC solar cell.

Are fs laser welds strong enough for a framed module?

The results show that the fs laser welds are strong enough for a suitably framed module to pass the IEC 61215 static load test with a load of 5400 Pa. Key to this finding is that the module must be framed and braced, and the glass must be ribbed to allow pockets for the cells and welds inside the border of the module.

Can femtosecond lasers form glass-to-glass welds?

Abstract: This article explores the use of femtosecond (fs) lasers to form glass-to-glass welds for hermetically sealed, polymer-free solar modules. Low-iron solar glass coupons were welded together without the use of glass filler using a fs laser with dedicated optics to elongate the focal plane parallel to the incident beam.
