Abstract:
1. A thin-film solar battery module manufacturing method, comprising: forming a first electrode layer on an insulating transparent substrate; forming a first isolation trench that isolates a peripheral region of the transparent substrate from a power generation region on an inner side thereof, to have a depth at which the first isolation trench reaches a surface of the transparent substrate; forming a semiconductor layer on the transparent substrate; forming a second electrode layer on the transparent substrate; forming a second isolation trench at a position closer to the peripheral region side than the first isolation trench, to have a depth at which the second isolation trench reaches the surface of the transparent substrate; and removing the first electrode layer, the semiconductor layer, and the second electrode layer formed in the peripheral region, by performing blast treatment on the peripheral region including the second isolation trench.
