Research Activities

The ISM-CNR X-ray Spectroscopy Laboratory is devoted to materials science studies; it is provided with different apparatus (both commercial and developed in-house) for materials and integrated systems analysis. The principal laboratory techniques available are: X-ray spectroscopy (both conventional and in Energy Dispersive mode), MicroRaman, AFM and complementary optical techniques (UV-Vis, FTIR). Specific focus is devoted to research activities in the field of Energy materials and devices (particularly for new generation photovoltaics, both organic and perovskite-based). Two in-hose developed apparata allow for structural/morphological studies of photovoltaic materials/devices:

• in-situ joint AFM/x-ray investigations provides bulk/interface/surface properties and aging effects.
• time-resolved X-ray spectroscopy under solar simulator, applied to photovoltaic systems, provides structural/morphological properties and aging effects under stress/working conditions.

The following apparata are available:

In-house research activity on Energy materials: structural and morphological properties optimization

Study, analysis and optimization of morphological / structural properties and phase transitions in innovative materials for energy

In-house research activity on new generation photovoltaics: active materials and aging effects

Studies of innovative materials and new generation photovoltaic devices (Perovskite photovoltaics, organic / plasmonic photovoltaics, hybrid organic / inorganic..): morphological-structural properties and aging processes.

Instrumentation development activity: implementation of x-ray, In-house development of spectromicroscopy advanced techniques (for in-situ / time resolved studies)
