dc.description.abstractIn this thesis, front side surface charge carrier collection for silicon thin-film solar cells and their impact on solar cell efficiency is evaluated, using advanced numerical device simulation combined with in-depth experimental characterization. Two types of thin-film solar cells are studied, namely hydrogenated amorphous silicon (a-Si:H) solar cells and solid phase crystallized polycrystalline silicon (poly-Si) solar cells on glass superstrates. Firstly, simulation models are developed and calibrated using measured reflectance, current-voltage and spectral response data of experimental solar cells. The electrical properties of the front charge carrier collection layers (window layer or emitter layer, respectively) of a-Si:H and poly-Si thin-film solar cells are then analysed (including effects from light scattering, material microstructures analysed by EBIC and EBSD method associated with SEM characterization) and their influences on solar cell efficiency are quantified. Finally, a device modification - the substitution of the highly recombination active layers by an ultra-thin tunnel layer with a high charge density at the interface with the silicon absorber layer - is evaluated numerically and the efficiency improvements potential of the new solar cell architectures are stated.
