6 FAQs about [Solar support deep processing and cutting]

Does laser cutting damage solar cells?

Most of the existing reports on solar cell cutting are focused on the laser wavelength, type, performance, and cutting parameters (depth of cut, speed, and direction of cut) to illustrate how to reduce the damage (hidden cracks, p-n junction leakage, and contamination) caused by laser cutting on solar cells [ 16, 17 ].

How does laser cut edge affect PERC solar cell recombination?

The laser cut edge causes a high recombination of the charge carriers, which negatively affects the pseudo fill factor as well as open-circuit voltage of the cell. The current work introduces two different approaches for passivating the laser separated PERC solar cells.

Should solar cells be cut into half-cells?

Over the past years, cutting solar cells into half-cells has grown to become a mainstream strategy in PV manufacturing. Significant gains in both power rating and mechanical strength at module level are demonstrated by using these technologies.

How does laser scribing affect solar cell performance?

A conventional cutting process is laser scribing, followed by a mechanical breaking process. This laser scribing method requires a deep scribing of approx. 30%-50% of the wafer’s thickness and causes a significant damaging of the solar cell edge in combination with microcracks. Both have a negative effect to the performance of the cell.

What is a loss at the edge of a solar cell?

The losses at the edges have a significant impact on the solar cell performance, particularly for high efficiency solar cells such as modern passivated emitter and rear cells (PERC), interdigitated back contact (IBC) cells, cells with tunnel oxide passivated contacts (TOPCon) or hetero junction cells (HJT) .

Can ATS structure be broken down during thin silicon solar cell fabrication?

However, the ATS structure is easily broken down during thin silicon solar cell fabrication, and it is important to note that it is not possible to prepare thinned 4-inch wafers with a thickness of <10 μm with ATS structure based on our experiments.
