We introduce passivating hetero‐interfaces in single‐junction microcrystalline silicon (μc‐Si:H) solar cells. We investigate the effect of different i–n layer stacks in thin μc‐Si:H devices, in which recombination is significant at the interfaces as well as in the bulk material. By applying amorphou...
