  • Publication number: 20120202313
    Abstract: 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).

  • Publication number: 20120199178
    Abstract: 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. The module has a first separating region separating the module into two sub modules along a first separating line running in the interconnection direction. The separating region includes: a first and a second isolation trench running parallel to one another and on both sides of the first separating line in the interconnection direction; a third isolation trench extending from the first isolation trench at least as far as the first separating line but not as far as the second isolation trench; and a fourth isolation trench extending from the second isolation trench at least as far as the separating line but not as far as the first isolation trench.

  • Patent number: 8187911
    Abstract: 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.

  • Patent number: 8021911
    Abstract: For producing a photovoltaic module (1), the front electrode layer (3), the semi-conductor layer (4) and the back electrode layer (5) are patterned by separating lines (6, 7, 8) to form series-connected cells (C1, C2, . . . Cn, Cn+1). The patterning of the front electrode layer (3) and of the semiconductor layer (4) is done with a laser (13) emitting infrared radiation. During patterning of the semiconductor layer (4) the power of the laser (13) is so reduced that the front electrode layer (3) is not damaged.

    Abstract: For producing a semitransparent photovoltaic module (1), the transparent substrate (2) is coated with a transparent front electrode layer (3), a semiconductor layer (4) and a metallic back electrode layer (5) and then partial areas (9) of the semiconductor layer (4) and of the back electrode layer (5) are removed. For this purpose, a stripping compound (14) is applied with an ink-jet printer (15) to the front electrode layer (3) on the areas (9) where the semiconductor layer (4) and the back electrode layer (5) are to be removed. Thereafter, the semiconductor layer (4) and the back electrode layer (5) are deposited on the stripping compound (4). Subsequently, the semiconductor layer (4) and the back electrode layer (5) are removed together with the stripping compound (14) from the front electrode layer (3) to form the translucent partial areas (9).

  • Patent number: 6274804
    Abstract: A thin-film solar module consists of a number of solar cells tandem mounted and series-connected on a common substrate and a number of diodes disposed antiparallel and adjacent thereto. Overlap zones are formed by a projecting edge area of an electrode layer of a solar cell or diode engaging a recess of the corresponding electrode layer of the adjacent diode or solar cell. Each diode is connected in the reverse direction with the adjacent solar cell in at least two overlap zones, the front electrode layer of the diode with the back electrode layer of the solar cell in at least one of said overlap zones, and the back electrode layer of the diode with the front electrode layer of the solar cell in at least one other overlap zone. The photovoltaically active layer sequence is additionally separated by grooves in areas of the grooves of the back electrode layer.
