Abstract :
Optical simulations were carried out in order to understand the effect of scattering at textured interfaces on the optical properties of a single junction a-Si:H solar cell. We used an optical numerical simulator for rite calculation of the absorption profiles in the solar cell. A sensitivity study of the influence of the model scattering parameters on the quantum efficiency of the a-Si:H solar cells was carried out and the most sensitive parameters were determined. From the calculated absorption profiles we have determined the losses in the non-active layers and the gain in the intrinsic layer of the solar cell
