(JP2001102604-A)   NOVELTY - The controlling method involves putting a mark, e.g. a two-dimensional code (3) in a peripheral region (2) on the front surface of a solar cell module (1). The code is put on that region of the front surface which is irradiated with the solar light. The peripheral region is not irradiated with a laser beam used for the laser scribing in the manufacturing process of the solar cell module. The two-dimensional code is put in the region that is not irradiated with a laser beam. The two-dimensional code is used for controlling the subsequent manufacturing process. Therefore, the code is put to the glass substrate before the glass substrate is subjected to the manufacturing process. The glass substrate with the code is used in various subsequent manufacturing steps.    USE - Method is used for controlling the manufacturing process in manufacturing solar cells of various specifications on a mass production basis.    ADVANTAGE - The manufacturing process of the solar cell and the quality of the product can be controlled consistently and efficiently.
