摘要：

A one-dimensional semi-coherent optical model for thin-film solar cells is presented. The optical circumstances at flat interfaces are addressed and the situation at rough interfaces in the model is described for the case of direct (coherent) incident and scattered (incoherent) incident light. After the model has been experimentally verified, analysis of the light scattering process in hydrogenated amorphous silicon (a-Si:H) p-i-n solar cells is carried out. The influence of the interface root-mean-square roughness and the effect of different angular distribution functions of diffused light on quantum efficiency and short-circuit current are investigated by the optical model.
