PRINTING DEVICE FOR SOLAR CELLS AND PANEL PRODUCTION METHOD

摘要

A printing apparatus (200) according to the present invention includes a printing section (220) configured to print ink on a surface (12) of a substrate (10). The printing section (220) prints conductive ink (Ka) containing a conductive material (Da) by offset printing and prints conductive ink (Kb) containing a conductive material (Db) different from the conductive material (Da) on the conductive ink (Ka) by offset printing. Preferably, the printing apparatus (200) further includes a conveyor (210) configured to convey the substrate (10). Further, the printing section (220) preferably includes a first printing machine (220a) configured to print first conductive ink and a second printing machine (220b) configured to print second conductive ink.
