METHOD AND IN-LINE PRODUCTION SYSTEM FOR THE PRODUCTION OF SOLAR CELLS

摘要

The invention relates to a method for the production of solar cells comprising the following steps providing (1) a semiconductor solar cell substrate, printing (2) a printing mixture containing a solvent and metal particles to form a printed mixture on the semiconductor solar cell substrate, drying (3) of the printed mixture at a drying temperature and over a drying duration, wherein both drying temperature and drying duration are chosen such that the solvent contained in the printed mixture is at least predominantly evaporated after the drying duration to obtain a metal structure and firing (4) the metal structure at a temperature of more than 570°C. According to the invention a resting time (T) of more than 20 seconds, preferably of more than 60 seconds, and more preferably of more than 120 seconds for the semiconductor solar cell substrate is provided for before the solvent of the printed mixture has evaporated by 10%, preferably by 5%, and more preferably by 2% of its total weight.
