NOVELTY - A photovoltaic cell comprises collector electrode (14) formed using electroconductive ink composition consisting of organic-type system containing electroconductive particle, heat-hardenable resin composition, hardening agent, and solvent in which electroconductive ink composition is used for screen-printing method. Mass ratio heat-hardenable resin composition:electroconductive particle is 2-15:75-95. Heat-hardenable resin composition uses epoxy resin composition which shows solid state at room temperature with melt viscosity at 150 degrees C of less than or equal to 0.5 Pa.s.    USE - A photovoltaic cell for solar cell module (claimed).    ADVANTAGE - Electrode has thin line, low resistance, sufficient adhesiveness in line-thinned small adherence area, excellent reliability and heat resistance, and sufficient hardening in a short heating time, and photoelectric conversion efficiency of solar cell module is improved.    DETAILED DESCRIPTION - A photovoltaic cell comprises collector electrode (14) formed using electroconductive ink composition consisting of organic-type system containing electroconductive particle, heat-hardenable resin composition, hardening agent, and solvent in which electroconductive ink composition is used for screen-printing method. Mass ratio heat-hardenable resin composition:electroconductive particle is 2-15:75-95. Heat-hardenable resin composition uses epoxy resin composition which shows solid state at room temperature with melt viscosity at 150 degrees C of less than or equal to 0.5 Pa.s. Electroconductive ink composition contains 20-40 mass parts heat-hardenable resin composition with respect to 100 mass parts solvent, and solvent is butylcarbitol, butylcarbitol acetate, butyl cellosolve, ethyl cellosolve, or alpha -terpineol. The collector electrode is formed on transparent conductive layer. An INDEPENDENT CLAIM is included for solar cell module containing a photovoltaic cell.
