    Ag and Sn Nanoparticles to Enhance the Near-Infrared Absorbance of a-Si:H Thin Films

    Silver (Ag) and tin (Sn) nanoparticles (NPs) were deposited by thermal evaporation onto heated glass substrates with a good control of size, shape and surface coverage. This process has the advantage of allowi...
