P. Zhang et al., ELECTROCHEMICAL DEPOSITION AND PHOTOVOLTAIC PROPERTIES OF NANO-FE2O3-INCORPORATED POLYPYRROLE FILMS, Synthetic metals, 84(1-3), 1997, pp. 165-166
Fe2O3 nanoparticles, of which sizes vary from 4 to 40nm, were introduc
ed into polypyrrole(PPy) films while pyrrole monomers were electrodepo
sited onto ITO electrodes. When measured in surface photovoltage spect
roscopy(SPS), new photovoltaic behaviors were observed in both cases c
ontaining small and large Fe2O3 particles. in terms of band structure
and polaron theory, together with the reference of absorption spectra,
some principles involved were revealed.
