Organic materials and devices for electronics, photovoltaics and sensors

This theme is dedicated to the field of organic electronics, with the aim to develop novel organic semiconductor devices for photovoltaic and sensor applications. The activity is highly multidisciplinary and relies on strong collaborations with teams from neighboring laboratories (ICPEES, ICS, IPCMS, IS2M). The group also established privileged relationships with other neighbouring teams through the network MATEOH-PV ("MAtériaux et TEchnologies Organiques et Hybrides pour le PhotoVoltaïque") in which our group plays a major role.
It is our main purpose to investigate the optoelectronic properties of novel organic materials, that have been designed and synthesised by chemists to fulfill a specific function (i.e. charge transport, light absorption, chemical recognition...), and to implement them as active material into dedicated devices. In order to carry out these studies, the laboratory recently acquired a technological platform to elaborate and characterise organic components under a controlled atmosphere. This platform is made up of several glove boxes that are coupled and equipped both with organic and inorganic thin film deposition tools (by wet process or vacuum evaporation) and characterisation instruments.
Three research topics are currently being considered: donor-acceptor bulk heterojunction solar cells for renewable electricity production, charge transport in organic semiconductors, and organic field effect transistors for chemical sensors.
