Commissariat à l’Energie Atomique et aux Energies Alternatives (CEA) is a French research-and-technology organization with activities in energy, information technology, healthcare, defense and security. CEA-Tech which is one of its divisions, focuses on creating value and innovation through technology transfer to its industrial partners. It operates 8,000-m² of state-of-the-art clean room space on 200mm and 300mm w
afer platforms and a printing platform called “PICTIC” dedicated to TOLAE activities. It employs 4,500 scientists and engineers including 300 Ph.D. students and 300 assignees from partner companies. CEA-Tech owns more than 2,200 patent families. Two departments will be involved in the PEROXIS project. The first one is the Optronics Department from CEA/LETI. Within this division, the Photonics Systems Laboratory (more than 30 persons including 5 PhDs) has a long experience in research and developments of X-ray and gamma-ray imaging detectors. Needs and specifications come from industrial customers who ask the lab to develop their own subcomponent that they will integrate in their imaging system. To fit with their requirements, a multidisciplinary approach from material to imaging is used. Skills in physics, modeling and simulation, electronics and information processing are associated with innovative technologies from other LETI Departments (ASIC design, innovative packaging, new material …) or sub-contractors. Today, the laboratory has a world recognized expertise in X-ray and gamma-ray imaging detectors for medical, security, and scientific applications based on semiconductor detection material operating at room temperature. The second one is the Printed Electronic Department from CEA/LITEN. With a team of more than 50 persons devoted to developments of hybrid organic-inorganic devices fabrication from solution, printing equipment, inks formulation, advanced devices characterizations, modeling and simulation, and device reliability. This department operates the French printing pilot platform PICTIC. Since 2010 it became one of Merck and Arkema testing laboratory for OSC and ferroelectric polymers. In 2011, the start-up ISORG was created from this department.
In the continuity of their R&D on organic photodiodes for X-ray indirect detection, CEA started to investigate perovskite materials for direct X-ray conversion with a special focus on self-supported perovskite single crystals grown from solution process. CEA aims to mature this technology and pushes it from the lab concept to concrete demonstrators. Within PEROXIS, CEA will coordinate the project, lead the WP3 dedicated to the fabrication of thick perovskite layers by the solution process approach, and will proceed to advanced characterizations through WP4 and WP5. CEA and others PEROXIS partners (Trixell, Philips, TNO, Institut Néel) have already demonstrated fruitful and complementary collaborations in the framework of others EU and non EU collaborative projects (LORIX, ROXTAR, PYCSEL), or bilateral R&D academic partnerships.
