LASER ASSISTED SEPARATION PROCESSES FOR BIFACIAL pSPEER SHINGLE SOLAR CELLS
In this paper, two laser-assisted separation processes (i) laser scribe and mechanical cleaving (LSMC) and (ii) thermal laser separation (TLS) for the separation of p-type silicon shingled passivated edge, emitter and rear (pSPEER) solar cells are examined. Both separation processes involve two process steps, where one of them is considered the main laser process that is
