Method for marking semiconductor component i.e. solar cell, of solar module, involves processing coded semiconductor substrate for producing conductor structure, where conductor structure is formed such that coding is readable

摘要

The method involves providing a flat, unprocessed semiconductor substrate (2) with a front side and a rear side (3). The rear side is provided with coding (4) using a laser method for producing coded semiconductor substrate. The coded semiconductor substrate is processed for producing a conductor structure on the rear side of the coded semiconductor substrate, where the conductor structure is formed such that the coding is readable. The structure is made of aluminum. The conductor structure is produced using a physical vapor deposition or chemical vapor deposition processes. An independent claim is also included for a solar module comprising a frame.
