METHOD FOR PRODUCING A CONTACT, A CONTACT AND SOLAR CELL COMPRISING A CONTACT |
摘要 |
Method for providing at least one contact on a back surface of a solar cell comprising a silicon substrate comprising depositing a passivating layer onto the silicon substrate and thereafter providing at least one contact site and further providing a patterned exposed silicon surface. Then depositing a metal layer and annealing the structure to form metal silicide. Thereafter the process involves optionally removing excess metal and finally applying metal onto the silicide to form at least one contact. A solar cell comprising a back surface, the back surface comprising a contact, produced by the above mentioned method. A contact for back surface of a solar cell comprising a silicon substrate, an amorphous silicon layer deposited onto the silicon substrate, a reflective layer with at least one opening deposited onto the amorphous silicon layer, in the at least one opening there resides silicide, with additional metal covering the silicide.
