A method of forming contacts on a surface emitter of a silicon solar cell is provided. In the method an n-type diffusion of a surface is performed to form a doped emitter surface layer that has a sheet resistance of 10-40 &#x3a9;/&#x25a1;. The emitter surface layer is then etched back to increase the sheet resistance of the emitter surface layer. Finally the surface is selectively plated. A method of fabrication of a silicon solar cell includes performing a front surface emitter diffusion of n-type dopant and then performing a dielectric deposition on the front surface by PECVD. The dielectric deposition comprises: The silicon is then annealed to drive hydrogen from the silicon nitride layer into the silicon to passivate the silicon.

Metallization method for silicon solar cells

A method of forming a contact structure and a contact structure so formed is described. The structure contacts an underlying layer of a semiconductor junction, wherein the junction comprises the underlying layer of a semiconductor material and is separated from an overlying layer of semiconductor material by creating an undercut region to shade subsequent metal formation. Various steps are performed using inkjet printing techniques.
