Project envisages to devise, but, before all, to optimise, thin film photovoltaic cells on the principle of donor-acceptor systems with charge-transfer, specifically with organic polymers and inorganic nanoparticles. The synthesis of polymers will be needed with appropriate long wave absorption in 600-800 nm region, and outstanding transport properties and stability, but before all nanomaterials with optimised absorption and transport properties will be needed. According to the results with cooperating foreign laboratories we will concentrate, besides standard polymer derivatives PPV(polyparaphenylene-vinylene) and P3HT (polythiofene), on new types of polysilafluorenes and on the percolation optimized nanostructures (quantum rods, tripods and nets) with ZnO and chalkogenides AIIBVI.The main goal will be to optimise electron devices of radiation by means of the minimization of the loss of photons, successive photoexcited excitons and photogenerated charge carriers. We are aiming at two application areas: sensors for the electromagnetic radiation in a wide spectral range 300 - 1200 nm for the general-purpose applications and photovoltaic cells for low cost applications, aiming at the techniques of stamping and nanoprinting of electronic circuits.
