Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of removing a peripheral part of a laminated film in a thin-film solar cell panel including its base layer by using a laser scribe method. SOLUTION: By irradiating the peripheral part of the laminated film of the thin-film solar cell panel having the laminated film having a transparent electrode film, a silicon film and a metal film on a transparent substrate formed on the base layer with a laser beam oscillated from a CW laser of output power ≥200W, the laminated film is removed over the whole circumference of the peripheral part including the base layer. The thin-film solar cell panel is manufactured by thus removing the thin film of the peripheral part. COPYRIGHT: (C)2010,JPO&INPIT
