Abstract
【解決手段】多数のシリコン太陽電池(4)の個別化方法において、第1の作業ステップでは、多数のシリコン太陽電池(4)を含むシリコンウェハに第1のレーザビーム(L1)により、分離線(5)に沿って、シリコンウェハ(2)内のpn接合(16)に隣接するシリコンウェハ(2)の前面(14)に、少なくともpn接合(16)に迄達する深さ(t)を有しかつシリコンウェハ(2)の側縁(24)に迄延びる溝(22)を形成し、第2の作業ステップでは、溝(22)に向けられる第2のレーザビーム(L2)により、シリコンウェハ(2)を側縁(24)から始めて分離線(5)に沿って切断し、切断中に生じる融解物(M)を、少なくともほぼ第2のレーザビーム(L2)の方向に流れる切断ガス(G)により、切断の際に生じる切断切り口(28)から追い払う。
