Scraping device for making the conductive lines of a photovoltaic cell

摘要

The invention relates to a scraping device used for producing parallel conductive lines by screen printing on a support (1) through a mask, said device comprising: N doctor blades (R_i), with N greater than or equal to 2, each doctor blade being defined by a row i, with i ranging from 1 to N, the N doctor blades being disposed adjacent and movable in translation to each generate one or more of said parallel lines, Height adjustment means associated with each doctor blade, A control system the scraper device which comprises, for each scraper of row i, an independent control module (MOD_i) configured to control its height adjustment means.
