In the course of developing amorphous silicon based solar cells, it is very important to know the profile of photo-generation rate in the device. This profile is strongly dependent on the optical properties of all the layers, the interface properties and the incident light spectrum. In the case of a solar cell with flat interfaces, the interference effect at long wavelengths should be taken into account. The light absorption can be optimized at a certain layer thickness. However, in the case of a solar cell with a textured substrate, the problem becomes more complicated since light will be scattered at several rough interfaces. The authors have studied the light scattering at the rough interfaces in typical amorphous silicon solar cells, developed a computer model to simulate the optical behavior of a multi-layer system with rough interface and simulated amorphous silicon based solar cells with different structures: glass/TCO/pin(a-Si:H)/Ag, glass/TCO/pin(a-Si:H)/pin(a-Si:H)/Ag, glass/TCO/pin(a-Si:H)/TCO/Ag, and ITO/pin(a-Si:H)/TCO/Ag. In this paper, the authors will present the method and the results of their optical modelling of amorphous silicon based solar cells. This modelling is performed for cells with flat or textured substrates.
