1. A method of passivating and reducing reflectance of a silicon photovoltaic cell, comprising the steps of:

  • a) providing a silicon wafer of a solar cell having a major surface;

    b) applying a passivation layer of silicon nitride on at least 98 percent of said major surface through a vacuum deposition process; and

    c) applying an index-matching film structure, different from silicon nitride, on top of the passivation layer;

    d) the index matching film structure providing the majority, of the antireflective property of the combination of the passivation layer and the index matching film structure.
