Hybrid Systems obtained through the alternation of semiconducting inorganic nano-particles (CdSe, PbSe) and organic semiconducting oligo-poly-conjugated molecules, bearing proper functionalization, were prepared.
By means f the Layer-by-Layer technique (LBL), self-assembled materials, organized as thin films on conductive and transparent surfaces, were prepared for Organic Photovoltaic applications (OPV). The materials combine the properties of both organic and inorganic semiconductors, but they have the advantage of being more flexible than the usually employed inorganic semiconductors and more resistant against oxidative degradation than the organic ones.
