Highly Luminescent Materials

Hybrid perovskites have led to a disruptive change in solution processed optoelectronic applications, with solar efficiencies exceeding 20%. Our research investigates the origin of the exceptional photophysics of this material class.

We found that radiative emission originates from efficient bimolecular recombination, and we demonstrated the world’s first lasing microcavity with hybrid perovskite as gain medium. Recently, we reported photon recycling in hybrid perovskites in Science.

Our findings put hybrid perovskites on par with the best current semiconductors, such as GaAs, and we seek to translate these findings to identify novel highly luminescent materials.
