  • Patent number: 5011782
    Abstract: The performance of a silicon photovoltaic cell is improved while process yield is maintained by first forming doped regions in a major surface of a silicon wafer and providing electrical interconnections to the doped regions prior to thinning the wafer by etching another major surface of the wafer. A passivating antireflection layer is applied to the etched surface after the surface is precleaned. The precleaning can be by ammonia plasma applied in situ as a precursor to depositing silicon nitride as the passivation layer.
