A PASTE COMPOSITION OF ELECTRODE FOR SOLAR CELL OF LOW TEMPERATURE HARDENING TYPE

摘要

The present invention relates to an electrode paste composition for a solar cell having a hardening property at low temperature. More specifically, when a screen printed electrode is hardened, a part of ITO substrate is selectively etched by adding an inorganic acid having an etching property and carbon black securing a dispersion property to the said composition so as to widen a contact area between the electrode and the ITO, to improve attachment strength and reduce contact resistance.
