摘要

The invention relates a full-laser scribing method for a flexible stainless steel substrate solar cell module, comprising: preparing an insulating layer and a molybdenum layer on a stainless steel substrate in sequence; using a laser I to scribe the prepared insulating layer and molybdenum layer to form a first scribed line (P1); preparing the following film layers in sequence on the molybdenum layer in which P1 has been scribed: a CIGS layer, a cadmium sulfide layer and an intrinsic zinc oxide layer; using a laser II to make scribe and thus form a second scribed line (P2), wherein the second scribed line P2 is parallel with the first scribed line P1; and preparing an aluminum-doped zinc oxide layer on the intrinsic zinc oxide layer in which P2 has been scribed, and using a laser III to make scribe and thus form a third scribed line (P3), wherein the third scribed line P3 is parallel with the first scribed line P1. The invention may avoid disadvantages caused by the screen printing, such as large dead zone, expensive screen printing paste and frequent replacement of screens for screen printing, thereby improve efficiency and stability of the module and save cost and increase production efficiency.
