The introduction of halide perovskites (HPs) have led to an unprecedented development in the energy field. As This new family of crystalline materials embraces numerous members with highly tunable chemical and physical properties. Especially, HPs can be made with truly hybrid compositions, where organic molecular cations are localized in ordered inorganic framework. This creates an interesting ‘playground’ for discovering functional materials and novel properties. As such, HPs have demonstrated the promise for various energy applications. Also important is the low-temperature, low-vacuum processability of these materials, making them highly suitable for both fundamental studies and real-world applications.

This proposed symposium will focus on linking basic sciences to energy technology commercialization. The topics will include new crystal/defect theories, multiscale structures, advanced characterizations, unusual carrier dynamics, solution or vapor phase synthesis, emerging interface sciences, (de)coupling of ionic and electronic behaviors, chemical stability, and quantum information sciences. The goal is to stimulate broad efforts in understanding basic perovskite sciences and their importance to the commercialization of perovskite-based energy technologies.
