6 FAQs about [Cutting photovoltaic panels with laser]
Is laser cutting suitable for solar cells?
It is suitable for solar cells with temperature-sensitive coatings, or depositions such as heterojunction devices. Germany's 3D-Micromac AG, a laser micro-machining and roll-to-roll laser systems supplier, has unveiled a new laser-cutting system for the production of half-cut and shingled solar cells.
Can thermal laser separation be applied to tunnel-oxide passivated contact shingle solar cells?
This work shows the first demonstration of thermal laser separation (TLS) and post-metallization passivated edge technology (PET) applied to tunnel-oxide passivated contact (TOPCon) shingle solar cells. The shingle solar cells with 26.46 mm × 158.75 mm size are separated from industrial full-square TOPCon host solar cells.
Why is half-cutting technology important in the photovoltaic industry?
In the photovoltaic industry, there are three critical parameters such as module power, cost and reliability. For increasing module power, half-cutting technology on the cell is one of the technologies because this can reduce the heating power by reducing the current.
Are cell-cutting processes becoming more ubiquitous in PV Manufacturing?
