SLIT COATING APPARATUS AND LAYER FORMING METHOD FOR FABRICATING SUB MODULE OF DYE SENSITIZED SOLAR CELLS

摘要

Disclosed are a thin film forming method and a slit coating apparatus for manufacturing a dye sensitized solar cell sub module with an improved method forming a thin film by a slit coating for comprising an element on a substrate. The slit coating apparatus comprises: a slit apparatus comprising at least one slit head comprising multiple nozzles formed with slits which move the substrate for forming the dye sensitized solar cell sub module, and discharge the coating raw material; and a supplying apparatus supplying more than two coating raw materials to the slit apparatus in two separate routes. The more than two coating materials are supplied independently to the multiple nozzles, which forms more than two coating films by the operation of the slit apparatus.
