Popis: The antireflection (AR) properties of Al 2 O 3 and Al x Ti 1―x O y films were investigated for the application of an AR coating of thin-film solar cells. Their optical transmittance was measured to exceed 85% over the entire visible and near-IR spectrum. The AR layers of these films coated on transparent conductive oxide (TCO)/Si exhibited 18% lower reflection than an uncoated TCO/Si at wavelengths from 400 to 900 nm. Furthermore, the thicknesses of the AR layers and TCO were demonstrated to influence the amount and shape of reflectivity in the reflection curves for the AR/TCO/Si structure.
