    Short Wavelength Response in a-Si:H p-i-n Diodes: A Simple Method to Minimize Interface Recombination

    Although single junction a-Si:H p-i-n solar cells with a conversion efficiency of about 12% have been demonstrated [1], the photo response of devices is limited by several factors. At short wavelengths, the mo...

    Absence of a Steady State in Hydrogen Diluted Silane Plasmas Due to Mass Dependent Gas Pum** Speeds and Its Consequences

    We have investigated the cause for continued changes in the silane related species observed using mass spectroscopy during i-layer deposition process lasting several tens of minutes. Silane decomposition is fo...

    Performance of a-Si-H Solar Cells at Higher Growth Rates

    We have studied the effects of external growth parameters during the deposition of the i-layers of a-Si p-i-n solar cells using dc plasma decomposition of silane-hydrogen mixtures at growth rates of up to 3A/s...

    He-Dilution to Increase Deposition Rate and Feedstock Utilization During the Growth of a-Si:H and a-SiGe:H Alloys

    We report on the development of helium diluted a-Si:H and a-SiGe:H solar cells with higher deposition rates and better feedstock utilization than devices made with hydrogen dilution. Both the initial and the s...
