Abstract
Photovoltaic module comprising a transparent substrate (1), a transparent front electrode layer (2), a semiconducting layer (3) of microcrystalline or micromorphous silicon and a rear electrode layer (4), said layers structured to form cells (C1, C2, C3) electrically separated by separating lines (5, 6, 7) and electrically connected in series. A laser beam (14) is used to generate at least in rear electrode layer (4) separating line sections (18, 18′) interconnected to form continuous separating lines (7) by connecting sections (19, 20) extending at an angle (α) to separating line sections (18, 18′).
Claims10
A method of making a photovoltaic module comprising a transparent substrate (1) and photovoltaically active layers, the latter comprising a transparent front electrode layer (2), a silicon semiconducting layer (3) and a rear electrode layer (4), said layers being structured to form individual cells (C1, C2, C3) electrically isolated from each other by separating lines (5, 6, 7) and connected in series, with the structuring at least of rear electrode layer (4) being carried out by means of a laser beam (14), characterized in that silicon semiconducting layer (3) consists of microcrystalline or micromorphous silicon and that laser beam (14) is used to generate at least in rear electrode layer (4) separating line sections (18, 18′) and connecting line sections (19, 20) extending at an angle (α) to separating line sections (18, 18′), said connecting sections connecting separating line sections (18, 18′) to form a continuous separating line (7).
