This report results from a contract tasking Moscow State University as follows Conjugated polymers are promising materials for many photonics applications, in particular, for photovoltaic and solar cell devices. This project will study the possibility to use conjugated polymers as active media in solar cell applications. The potential advantages of conjugated polymers solar cells CPSC are the electronic properties of conjugated polymers can be tuned to match the solar spectrum, the intrinsic absorption index of some conjugated polymers could be higher than silicon for large part of the solar spectrum, large area thin films on flexible substrates could be prepared, and the production cost could be lower than for inorganic solar cells. At the same time, the known disadvantages of CPSC are free carriers are not excited directly under solar irradiation, the mobility of free charges is low and very different for opposite polarity, low stability of conjugated polymers to oxidation and photo-oxidation. This project will use poly-para-phenylene-vinylene, vacuum deposited poly-para-phenylene and their donor-acceptor complexes to realize the advantages of CPSC and to neutralize their drawbacks. The goals of the project are to find a class of conjugated materials most promising for solar cell applications and then to study CPSC prototypes, which will be optimized for high efficency.
