電極形成用ガラスフリット、およびこれを用いた電極形成用導電ペースト、太陽電池

摘要

To provide a glass frit for forming an electrode, to be used for forming a light-receiving surface electrode for a solar cell, which has suitable glass fluidity and Si reactivity required to form a light-receiving surface electrode and a sufficient water resistance. A glass frit for forming an electrode to be used for forming a light-receiving surface electrode 12 for a solar cell 1, which comprises from 3 mol % to 20 mol % of SiO2, from 10 mol % to 40 mol % of Bi2O3, from 15 mol % to 45 mol % of B2O3, from 10 mol % to 60 mol % of ZnO and from 2 mol % to 10 mol % of Ti2O, wherein the total content of Bi2O3 and ZnO is from 35 mol % to 70 mol %.
