Enabling the rational design of chiral hybrid perovskites: a combined computational-experimental approach (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, transistors, and photodetectors. Recently, the versatility of HOIPs has been further expanded through the incorporation of chiral organic cations, creating chiral hybrid perovskites (CHPs). CHPs present a novel class of solution-processable chiral semiconductors for use in optoelectronic devices that make use of chiral optical and electronic properties, chiroptoelectronics. Their selectivity with regard to the absorption of left- or right-handed circularly polarized light (CPL), a property called circular dichroism, makes them extremely promising candidate active materials for applications like CP-photodetectors. Such photodetectors could cause breakthroughs in remote sensing, and optical imaging and communication. Though CHPs possess strong application potential, the field is still in its infancy, and many fundamental questions remain unanswered. The aim of my Ph.D. project is to perform a systematic combined computational-experimental study of CHPs in order to obtain structure-property relationships that can be used to guide rational material design toward their applicability in chiroptoelectronics.
