Prof. Jean Roncali received his Ph.D. in 1984 in Paris under the supervision of Francis Garnier.After successive positions as engineer and researcher in the Laboratory of Molecular Materials of CNRS,in 1991 he moved to the University of Angers to create the Linear Conjugated Systems Group as Research Director.Jean Roncali has received the Grammatikakis-Neuman Prize of the French Academy of Sciences in 2002, the Pierre Süe Great Prize of the French Chemical Society in 2008 and Prix Euranet Inner Idea Lab in 2009
Although the conversion efficiency of organic solar cells has recorded impressive progress in recent years with values now rivaling those of inorganic solar cells, the industrial development of this technology remains elusive and the topic seems to remain confined to a purely academic interest. After a brief introduction exposing personal views on the possible causes of this situation. The potential advantages of single material organic solar cells (SMOSCs) will be discussed. The state-of-the-art of the different approaches and concepts developed for SMOSCs fabrication including double-cable polymers, block copolymers and molecular dyads will be presented. A particular emphasis will be given to the recently emerging topic of homojunction SMOSCs. Some preliminary results on homojunction cells based on small donor-acceptor molecules will be presented and possible directions for future research will be discussed.
