SQUAP

The new research activities of part of the team focus on studying emerging materials relevant for photovoltaic applications, in particular perovskites. In this way, our activities fit with the objectives of DIM MaTerRE, especially concerning the theme of new energy recovery methods. We aim at highlighting and understanding the fundamental properties of perovskites, such as carrier dynamics and the formation of electron-phonon quasi-particles called “polarons,” which significantly impact carrier mobility and, consequently, performance for solar cell applications. To achieve this, we have developed cutting-edge time-resolved spectroscopy techniques, such as time-resolved terahertz spectroscopy and time-resolved Raman spectroscopy, which allow us to characterize the transient state of charge carriers and the material structure at very short times after photo-excitation. This fits with the methodological axis on advanced characterization techniques of DIM MaTerRE
