Ph.D. proposal n°1: Ink formulation for prignatniicg soorlar cells on large areasOrganic optoelectronic devices (light emittinge sd,i odsolar cells, transistors) are processed from low molecular weight organic molecules uogr atceodn jpolymers. Some of these materials can be soluble, and in that case, can be procreinstsiendg bteyc hpnologies using inks. This feature makesorganic materials interesting to develop at lto wf lecxoibsle devices on large areas. Several printingtechnologies have been successfully exploited vteol opd eprototypes, but the obtained devices still suffer from several important limitations, sucrhe duacse d performance, poor stability and reproducibility. Different solutions addressings et hiessues exist: the use interfacial layers ieor r barrlayers, the development of new organic moletchu leism pwroived properties, the formulation of inks including nanoparticles, etc. Some of these nss olaurteio still far from being validated, and other approaches have still to be explored.
