Abstract This work shows the first demonstration of thermal laser separation (TLS) and post‐metallization passivated edge technology (PET) applied to tunnel‐oxide contact (TOPCon) shingle solar cells. The cells with 26.46 mm × 158.75 size are separated from industrial full‐square TOPCon host singulation is performed either by TLS front side (emitter side) or conventional scribe mechanical cleaving (LSMC) rear (emitter‐free side). optimized in this yields up 0.2% abs more efficient after...
This work deals with solar modules made from rectangular-shaped cell strips, so-called shingles, that are interconnected by overlapping one another. For the fabrication of such modules, host cells cut into several shingles resulting in unpassivated shingle edges and relevant recombination losses. As discussed this based on simulations, quantifying these losses module level is not straightforward ideally done referring to pseudo fill factor pFF. In context, it shown passivating depositing a...
