Yangzhou University researchers develop laser-assisted patterning for TOPCon solar cells
UNVERIFIED·Primary source · PV Magazine
Researchers developed a laser-modification and KOH wet-etching process for rear poly-finger contacts.
The method improves efficiency by reducing parasitic absorption in TOPCon solar cells.
The champion cell achieved 26.08% efficiency, certified by ISFH.
