Publication number: 20120202313Abstract: For forming the separating lines, (5, 6, 7) which are produced in the functional layers (2, 3, 4) deposited on a transparent substrate (1) during manufacture of a photovoltaic module with series-connected cells (C1, C2, . . . ), there are used laser scanners (8) whose laser beam (14) produces in the field (17) scanned thereby a plurality of adjacent separating line sections (18) in the functional layer (2, 3, 4). The laser scanners (8) are then moved relative to the coated substrate (1) in the direction (Y) of the separating lines (5, 6, 7) by a distance corresponding at the most to the length (L) of the scanned field (17) to thereby form continuous separating lines (5, 6, 7) through mutually flush separating line sections (18).Type: ApplicationFiled: September 9, 2011Publication date: August 9, 2012Applicant: Schott Solar GmbHInventor: Walter Psyk

Publication number: 20120199178Abstract: A raw module is provided that includes a substrate, a front electrode layer, a semiconductor layer, and a rear electrode layer. The layers are separated by structuring trenches into sub cells, which are electrically connected in series in an interconnection direction.

Patent number: 8187911Abstract: For forming the separating lines, (5, 6, 7) which are produced in the functional layers (2, 3, 4) deposited on a transparent substrate (1) during manufacture of a photo-voltaic module with series-connected cells (C1, C2, . . . ), at least one laser scanner (8) is used whose laser beam (14) produces in the field (17) scanned thereby a plurality of separating line sections (18, 18?) disposed side by side in the functional layer (2, 3, 4). The laser scanner (8) is moved relative to the coated substrate (1) in the direction (Y) of the separating lines (5, 6, 7), thereby giving rise to an overlap (36) of adjacent fields (17, 17?). At the same time, the laser scanner (8) produces separating line sections (18, 18?) which are of hook-shaped configuration at least at one end (32) so as to form a catching area in which the ends (31, 32) of the separating line sections (18, 18?) of adjacent fields (17, 17?) overlap.Type: GrantFiled: March 12, 2009Date of Patent: May 29, 2012Assignee: SCHOTT Solar AGInventor: Walter Psyk
