Abstract

New features of the ASA software package are described that allow the analyses of the performance of hydrogenated amorphous silicon (a-Si:H) based solar cells with rough interfaces and buffer and graded layers. Using the updated version of ASA improved understanding of i) the effect of the front and back contact roughness on the external quantum efficiency and the absorption of light in the individual layers of a-Si:H solar cells and ii) the role of band gap grading of the intrinsic a-SiGe:H layer in a solar cell is obtained. The simulated results using the ASA package agree well with measured data on solar cells and are used to give insight into the behavior of the internal parameters of the solar cells.
