<p>PROBLEM TO BE SOLVED: To provide a reliable rear-surface sealing method of a thin-film solar cell. SOLUTION: A laminated body is provided in which, on the rear surface of a thin-film photoelectric conversion unit layer 2 formed on a glass substrate 1, a local junction resin sheet 3a and an insulating sheet 4 comprising a nonwoven fabric are laminated, over which a metal foil 5 for internal electric wiring is stacked with no use of a local junction resin sheet 3b, and further, an entire junction resin sheet 3c covering the entire region of the thin-film photoelectric conversion unit layer 2 and a sealing glass rate 6b are sequentially laminated. The laminated body is placed on the hot plate of a vacuum laminator for vacuum-exhausting, and the sealing glass plate 6b is pressurized by a diaphragm in the laminator after the junction resin sheets 3a and 3c are melted, before eventually curing the junction resin.</p> |
