STUDY OF AQUEOUS-PROCESSABLE FULL-ORGANIC AND HYBRID ORGANIC/INORGANIC NANOPARTICLE-BASED FILMS FOR SUSTAINABLE PHOTOVOLTAIC APPLICATIONS

Organic photovoltaic offers energy from a widely available and naturally replenished source, with relevant advantages of low-cost, easy fabrication, solution processability, light weight, transparency, and mechanical flexibility. Unfortunately the huge use of harmful halogenated aromatic solvents in the processing together with that of a critical metal as Indium is in the transparent electrode, have limited the industrial implementation of this technology so far. We developed an aqueous ink made of nanoparticles of blended semiconducting polymers/fullerene derivative to fabricate the active layer, and tried to deposit it onto an electrode made on Silver nanoparticles prepared in a PS-co-P4VP matrix and then blended with PEDOT. Different deposition methods were tried, spin coating and micro-contact printing and the prepared films were characterized by AFM ,TEM etc.
