Synthèse et étude de chromophores organométalliques pour cellules solaires hybrides à colorant et à hétérojonction volumique

Abstract : Today the sustainable energy production and research for alternatives to non-renewable sources attract a lot of interest. The aim of this PhD research was to synthetize and study new organometallic complexes Ru-diacetylide based, then to characterize their photovoltaic properties in hybrid dye-sensitized and organic bulk-heterojunction solar cells. To obtain panchromatic chromophores, asymmetric bimetallic complexes have been designed using [Ru(dppe)2] unit as excellent electron relay in a “push-pull” structure. In parallel, symmetric complexes have been developed with one or two metallic centres, and then they have been integrated to organic bulk-heterojunction solar cells. For this study, each device has been optimized through different steps, in order to improve charges transfers by improving morphology of the active layer. The main methods of optimization applied consisted of application of “solvent vapor annealing” treatment, addition of structure additives and addition of the dye in polymer matrix, in ternary molecules blend device.
