Among several types of “passivated contacts”, the combination of an ultrathin dielectric and a doped polysilicon layer can simultaneously give low recombination and resistive losses, that is, form an effective carrier-selective contact for solar cells.
In advanced silicon solar cells, surface passivation is usually achieved by means of thin layers of dielectric or semiconducting materials.

Other studies of ion implanted and thermally activated polysilicon layers have demonstrated very low recombination current densities J0 ∼1 fA/cm 2 for n + polysilicon and ∼4.4 fA/cm 2 for p + polysilicon , , which shows the great potential of doped polysilicon as a passivated contact for solar cells.
