Document Type and Number:
WIPO Patent Application WO/2023/115716
Kind Code:
A1
Abstract:
A conductive paste composition, a preparation method therefor and an application thereof, and a crystalline silicon solar cell. The conductive paste composition contains silver powder and aluminum powder, and contains a lead-boron-selenium glass frit or a bismuth-boron-selenium glass frit. The conductive paste composition can well etch a passivation film of an n-type crystalline silicon solar cell during high-temperature sintering, and aluminum powder contained in the conductive paste composition cannot be excessively oxidized, and an electrode in good electric contact with a p-type doped emitter can be formed.
