His research focuses on the study and fabrication of electronic and optoelectronic devices, their analysis and their optimization. An important aspect of the research concerns the simulation of micro and nanoelectronic devices. The development of the non-equilibrium theory for the microscopic description of the transport process in nanostructured devices and its multiscale implementation has been the subject of invited talks at international conferences and University seminars. In recent years his research was particularly focused on the development of organic solar cells, in particular Dye Solar Cells and Pervoskite Solar Cells, and on scaling-up of these technologies for industrial applications. Di Carlo founded and direct (2007-2019) of the Center for Hybrid and Organic Solar Cells (CHOSE) which involve more than 30 researchers. CHOSE has generated 5 spin-off company and a public/private consortium for-industrialization of DSC cells.
