摘要
We have measured for the first time the band lineup at the interface between boron-doped p-type hydrogenated amorphous silicon (a-Si:H) and crystalline silicon (c-Si) by internal photoemission and have found that the band discontinuity mainly exists on conduction-band (CB) side in this type of heterojuctions. This band lineup is related with the low back-surface recombination velocity observed in n(+)(c-Si) - p(c-Si) - p(+)(a-Si:H) solar cells.
