1. A method for fabricating a photovoltaic structure, the method comprising:

  • obtaining a Si substrate;

    forming an emitter layer on a first surface of the Si substrate;

    depositing, using a physical vapor deposition machine, a transparent conductive oxide layer on the emitter layer;

    depositing, without removing the Si substrate from the physical vapor deposition machine and without first annealing the deposited transparent conductive oxide layer, a metallic layer on the transparent conductive oxide layer; and

    annealing the transparent conductive oxide layer after depositing the metallic layer.
