Electro-conductive paste for forming an electrode of a solar cell device, a solar cell device and method for producing the solar cell device

摘要

In order to provide an electro-conductive paste bringing no increase of the contact resistance for forming an electrode of a solar cell device, the electro-conductive paste is characterized by containing an electro-conductive particle, an organic binder, a solvent, a glass frit, and an organic compound including alkaline earth metal, a metal with a low melting point or a compound affiliated with a metal with a low melting point.
