      abstract     = {We present an experimental study combined with computer
                      simulations on the effects of wide band-gap absorber and
                      window layers on the open-circuit voltage (Voc) in single
                      junction thin film silicon solar cells. The quantity ΔEp,
                      taking as the difference between the band gap and the
                      activation energy in ⟨p⟩ layer, is treated as a measure
                      of the p-layer properties and shows a linear relation with
                      Voc over a range of 100 mV with a positive slope of around
                      430 mV/eV. Two limiting mechanisms of Voc are identified:
                      the built-in potential at lower ΔEp and the band gap of the
                      absorber layer at higher ΔEp. The results of the
                      experimental findings are confirmed by computer
                      simulations.},
