Abstract: Conductive layer(s) in a thin film photovoltaic (TFPV) panel are divided by first scribe curves into photovoltaic cells connected in series. At least one of the layers is scribed to isolate a shunt defect in a cell from parts of that cell away from the defect. The isolation scribes can substantially follow or parallel current-flow lines established by the design of the panel. A TFPV panel can be altered by, using a controller, automatically locating a shunt defect and scribing at least one of the conductive layers along two spaced-apart second scribe curves. Each second scribe curve can intersect the two first scribe curves that bound the cell with the defect. The two second scribe curves can be on opposite sides of the defect.

Abstract translation: 薄膜光伏（TFPV）面板中的导电层由第一划线曲线划分成串联连接的光伏电池。 划分至少一个层以将细胞中的分流缺陷与该缺陷的部分隔离。 隔离扫描仪可以基本上跟随由平板设计建立的并行电流线。 TFPV面板可以通过使用控制器自动定位分流缺陷并沿着两个间隔开的第二划线曲线划分至少一个导电层来改变。 每个第二划痕曲线可以与将缺陷细胞结合的两个第一划线曲线相交。 两个第二划线曲线可以在缺陷的相对两侧。
