| 摘要 |
A lead-free conductive paste composition for a solar cell contains a conductive powder, a glass frit, and a vehicle, the glass frit including at least one type of lead-free glass containing Bi2O3 from 10 to 32 (mol %), ZnO from 15 to 30 (mol %), SiO2 from 15 to 26 (mol %), B2O3 from 5 to 18 (mol %), Li2O, Na2O, and K2O from 12 to 25 (mol %) in total, Al2O3 from 2 to 10 (mol %), TiO2 from 0 to 6 (mol %), ZrO2 from 0 to 5 (mol %), 0 to 6 (mol %) P2O5 and 0 to 4 (mol %) Sb2O3 making a total of 0 to 6 (mol %), and CeO2 from 0 to 5 (mol %) at proportions within the respective ranges relative to the whole glass composition in terms of oxide. |
