Abstract
Provided is a conductive paste for forming a solar cell electrode containing a glass frit component (A) as glass frit (II), the glass frit component (A) containing the following in the content ratio to the total molar number in terms of oxide: (a) 30 to 70 mol % of tellurium element, (b) 18 to 30 mol % of tungsten element, (c) 5 to 30 mol % of zinc element, (d) 1 to 15 mol % of boron element, (e) 0.3 to 5 mol % of aluminum element, The conductive paste may have better electric characteristics and a small variation in the characteristics even at a relatively low firing temperature (for example, 760° C.).
