Hybrid perovskites with a twist: inducing chirality towards circularly polarized light emission (Research)

Hybrid perovskites (HOIPs) have seen an unprecedented rise in the power conversion efficiency of their solar cells over the past decade. Their success as solar cell materials has sparked the exploration of this versatile class of hybrid materials for other optoelectronic applications such as light-emitting diodes (LEDs), photodetectors, transistors, and lasers. Recently, the versatility of HOIPs has been expanded again by incorporating chiral organic cations, creating chiral hybrid perovskites (CHPs). CHPs present a novel class of solution-processable chiral semiconductors. Since they can emit circularly polarized (CP) light with a tunable wavelength depending on their composition, they can be used as active materials in CP-LEDs. CP-LEDs could revolutionize (3D) displays and (medical) imaging. Though CHPs are highly promising, the field is still in its infancy, and many open questions remain. The aim of my Ph.D. project is to perform an in-depth study of CHPs in order to obtain structure-property relationships that can be used to guide research efforts in a rational way toward the improvement of their properties for use in CP-LEDs.
