abstract = {We report on a plasmon-induced photocurrent in
photosensitive devices based on hydrogenated amorphous
silicon (a-Si:H) containing silver nanoparticles (NPs). The
photocurrent is measured in a spectral region corresponding
to optical transitions below the band gap of a-Si:H.
Photoexcitation of “hot” electrons in the NPs or in
defect states present in the vicinity of the NPs, resulting
from plasmon decay in the NPs, is often cited as being
responsible for this effect. In this study, we demonstrate
that plasmon induced photogeneration of “hot” holes is
also able to contribute to a photocurrent. A bifacial
symmetrical transparent device was prepared in order to
compare the internal quantum efficiency of both processes,
the first based on the photogeneration of “hot”
electrons and the second based on the photogeneration of
“hot” holes.},
