Optics and Materials : Quantum and Nano

The research carried out by the team at the LuMIn laboratory focuses on the study of the optical, photonic, and ultrafast properties of functional materials for energy applications, with particular emphasis on hybrid and inorganic halide perovskites, investigated as thin films, crystals, nanoparticles and low-dimensional (2D/3D) systems. The team investigates the fundamental mechanisms of charge carrier generation, transport, and recombination, electron–phonon interactions, and the effects of defect passivation in perovskite thin films, which represent major limiting factors for photovoltaic applications. This work combines advanced optical spectroscopies, resolved in time from the femtosecond to the microsecond range, with photonic approaches (optical cavities, confined structures), in order to establish direct links between material architecture, excitation dynamics, and energy performance.

Within the framework of MaTerRe, the team contributes to the understanding and optimization of innovative semiconductor materials for solar energy conversion, addressing key challenges related to stability, durability, and efficiency. The research also explores alternative strategies, such as low dimensionality and photonic engineering, to enhance performance while limiting environmental impact. Overall, the team’s activities are fully embedded in a materials science approach for the energy transition, bridging fundamental properties and applications.
