NANOPARTICLE INKS FOR SOLAR CELLS

摘要

In a process for producing a solar cell, a sintering process performed on a nickel nanoparticle ink forms nickel silicide to create good adhesion and a low electrical ohmic contact to a silicon layer underneath, and allows for a subsequently electroplated metal layer to reduce electrode resistances. The printed nickel nanoparticles react with the silicon nitride of the antireflective layer to form conductive nickel silicide.
