POLYIMIDE RESIN COMPOSITION FOR USE IN FORMING INSULATION FILM IN PHOTOVOLTAIC CELL AND METHOD OF FORMING INSULATION FILM IN PHOTOVOLTAIC CELL USED THEREWITH

摘要

Disclosed are a polyimide resin composition for use in forming an insulation layer in a photovoltaic cell, a method of forming an insulation layer in a photovoltaic cell used therewith, and a photovoltaic cell having an insulating layer formed by the method, that have an optimal rheological property for screen printing and the like, allow wettability of each coated substrate to be improved, are capable of continuous printing 500 or more times, and can coat a predetermined area without solvent boil, cissing or pinholes being produced after printing and coating or when drying and curing. The polyimide resin composition for use in forming an insulation film in a photovoltaic cell is a heat-resistant polyimide resin capable of melting in a mixed solvent of a first organic solvent (A) and a second organic solvent (B), wherein the polyimide resin containing an alkyl group and/or a perfluoroalkyl group in repeating units of the polyimide, and having a thixotropic property, is included in the mixed solvent.
