Method for Fabricating Crystalline Silicon Solar Cell Having Passivation Layer and Local Rear Contacts

摘要

The present invention is a method for fabricating a crystalline silicon solar cell having a passivation layer and a plurality of local rear contacts, which comprises steps of forming a passivation layer on the rear surface of the silicon substrate; coating distributed metal electrodes on the rear surface and forming a plurality of local rear contacts through firing and forming a metallic reflector at the rear surface so that the metallic reflector electrically contacts with the plurality of local rear contacts.
