PROCESS FOR PRODUCING CONDUCTIVE PASTES FOR FORMING SOLAR CELL ELECTRODES

摘要

A process for producing conductive pastes for forming solar cell electrodes, including a step of measuring binding energies of oxygen in a glass frit by X-ray photoelectron spectroscopy, a step of selecting a glass frit providing an X-ray photoelectron spectrum representing binding energies of oxygen in which the signal intensity of a peak with a peak top at a range from 529 eV to less than 531 eV has a proportion of 40% or more relative to the total of signal intensities from 526 eV to 536 eV, and a step of mixing together a conductive powder, the glass frit and an organic vehicle.
