Recombination mediated by band tail states is shown to substantially reduce the maximum achievable output voltage in amorphous silicon hydride solar cells. The maximum open circuit voltage calculated from measured density of states parameters and reasonable estimates for the localized state capture rates is 1.0±0.1 V.
