The role of Softness in the Physics of Defects: Probing Buried Interfaces in Perovskites Optoelectronic Devices
SOPHY will develop tools and knowledge to probe optoelectronic processes at buried interfaces delivering a long time pursued target in many fields of nanotechnology. Semiconducting metal halide perovskites, and devices based on them, will be the primary technology under investigation, given its potential to represent the merging point between the efficient inorganic and the chameleonic organic electronics. These materials have a characteristic structure prone to a wide set of defects, sensitive to the device operating conditions. The control of structure-properties relationship, especially at interfaces, is elusive, and the prediction of device operation, necessary to engineer reliable systems, is not possible without an “in vivo” approach. SOPHY addresses the above challenge by putting in place an experimental tool which will film the physical processes of an optoelectronic device in action.
