    Scattering Distribution of Light fromthin Film Rough Layers &Layer Stacks for a-Si:H Solar Cells
    (Addis Ababa University, 1997-06) Berga, Tadesse
    Reflectance(R), Transmittance(T), and Scattering distribution of thin film TCOs and with their p-I (thin & thick) i-layer stacks have been measUred for various wavelengths. The shape of scattering distributions have been determined by using an easy plot software. The functional dependence of normalised intensity on - wavelength (A) and scattering angle (8) have been detennined for Asahi U & Standard TCO. The thickness of individual layers was determined from reflectance & transmittance measmements by using an optical simulation software for layer stacks. The diffused transmittance determined from transmittance measmement and scattering distribution measmements have been compared
