Conductive paste and solar cell using the same

摘要

A conductive paste contains conductive powder and an organic vehicle. The conductive powder includes aluminum powder having an average particle diameter of 2 to 10 mu m and having an oxide layer with a thickness of 2 to 10 nm on the surface thereof. A solar cell includes a silicon substrate having a light-accepting surface, a light-accepting-surface electrode formed on the light-accepting surface of the silicon substrate, and a back-surface electrode formed of the conductive paste described above.
