High-efficiency solar cell technologies rely on a sound knowledge of interface engineering and characterization on an atomic scale. Electrical interface recombination losses are closely related to structural and chemical properties of passivation layers. Ultra-thin silicon oxide layers (thickness about 1 nm, often referred to as tunnel oxide layers) applied in the recently
