The EU-Project LARGECELLS focuses on the development of organic photo voltaic cells based on innovative conjugated polymers materials, polymer-inorganic hybrid systems and their usage in large area devices fabricated using printing techniques. A concerted parallel screening, using both out-door and indoor tests of life-time and degradation mechanisms, will help to design the best materials for highly efficient and stable devices. Progress in these areas will enable the preparation of more efficient modules far beyond today`s state of the art and help to generate knowledge and IP for European players. The interaction with an excellent Indian consortium paves the infrastructure for the first time in such a vital technology with long-term perspectives.

The task of developing large-area, thin film solar cells based on polymers as well as solid-state organic-inorganic (hybrid) systems will be undertaken. The required novel materials (charge transport polymers, semiconductor surfactants/compatibilizers and inorganic nanoparticles) will be synthesized and the compounds with the most potential will be scaled-up for the purpose of modern fabrication methods such as roll-to roll (R2R) processing. Additionally, the efficient devices will be tested and analyzed in out-door conditions in India and under accelerated ageing conditions in Israel to understand the degradation mechanism. Finally the basic information from stability studies will be used to design novel materials suitable for highly efficient devices of long-term stability.

The programme is intensively intertwined with an Indian consortium, especially in the fields of novel materials, out-door testing, transfer and exchange of knowledge and methods.

Dr. Eugene Katz and Ben-Gurion University of the Negev are one of five universities in the consortium.
