Acrylic binder for solar cell electrode paste with excellent printing characteristics and solar cell electrode paste using same

摘要

PURPOSE: An acrylic binder is provided to have viscosity sufficient for coating, to uniformly disperse glass powder and conducting metal, and to maintain the shape of an electrode until sintering. CONSTITUTION: An acrylic binder having excellent printability is manufactured by polymerizing an acrylic monomer and a copolymerizable reactive monomer having a reaction group with excellent printability, represented by chemical formula 1 or 2, under the presence of an organic solvent and a polymerization initiator to introduce the reaction group with excellent printability into an acrylic polymer chain. In chemical formula 1, R is hydrogen or a linear or branched alkyl group. In chemical formula 2, R is a hydrogen atom or a linear or branched alkyl group.
