摘要

The impacts of p-layer bandgap E_p on the V_(oc) of a-Si:H solar cells were investigated by experiments and numerical simulations using AMPS model developed at Perm State University. Using a high hydrogen dilution and a high gas pressure, as well as a high RF power density of at a low substrate temperature of 70℃, we got nanocrystalline silicon (nc-Si:H) p-layers with wide bandgap up to 1.9 eV . It is found that the nc-Si:H p-layer with a certain nanocrystalline volume fraction, within the range studied, leads to a higher Voc.
