We present a study on photovoltaic devices based on polypyrrole (PP) and SiC nanoparticles (~30 nm) in the matrix of poly(N-vinylcarbazole) (PVK). The photovoltaic cell structure was ITO/(polymer with SiC)/Ca/Al. The photophysics of such photoactive devices is based on photoinduced charge transfer from donor-type semiconducting conjugated polymers to acceptor-type SiC nanoparticles. The process mimics early photo effects in natural photosynthesis. In the general context of organic photovoltaics, polymeric materials have a cutting edge since they combine the photoelectrical properties of semiconductors with the large scale/low cost technology of polymeric materials.
