METHOD OF MANUFACTURING THIN-FILM PHOTOVOLTAIC MODULE

摘要

A method of manufacturing a thin-film photovoltaic module in which a photoelectric conversion element is deposited on a substrate, includes removing the photoelectric conversion element at a frame shape area from sides of the substrate toward inside with a predetermined width by a first removing step of scanning a first photoelectric conversion element removing device at the area along the sides of the substrate to remove the photoelectric conversion element for the predetermined width, and a second removing step of scanning a second photoelectric conversion element removing device within the area along the sides of the substrate to remove the photoelectric conversion element that is not removed in the first removing step at a width narrower than the predetermined width and without superimposing a center line of a scanning path on a center line of a scanning path of the first photoelectric conversion element removing device.

主权项

1. A method of manufacturing a thin-film photovoltaic module in which a photoelectric conversion element is deposited on a substrate and insulation properties of a peripheral portion of the substrate is ensured,
the photoelectric conversion element including a first electrode layer, a thin-film photoelectric conversion layer and a second electrode layer stacked in this order, the method comprising removing the photoelectric conversion element at a frame shape area from sides of the substrate toward inside with a predetermined width, the photoelectric conversion element being deposited on the entirety of the substrate, by
a first removing step of scanning a first photoelectric conversion element removing device at the area from the sides of the substrate toward inside with the predetermined width along the sides of the substrate to remove the photoelectric conversion element deposited on the substrate for the predetermined width, anda second removing step of scanning a second photoelectric conversion element removing device, within the area at which the photoelectric conversion element is removed in the first removing step, along the sides of the substrate to remove the photoelectric conversion element that is not removed in the first removing step at a width narrower than the predetermined width and without superimposing a center line of a scanning path on a center line of a scanning path of the first photoelectric conversion element removing device in the first removing step.
