Solar cells based on hybrid perovskites (HOIPs) have shown an unprecedented increase in efficiency over the past decade. This success as solar cell materials has also fuelled further research into HOIPs for other optoelectronic applications, such as LEDs, transistors and photodetectors. Recently, these versatile materials have become even more versatile through the integration of chiral organic cations, giving rise to chiral hybrid perovskites (CHPs). This new class of solution-processable chiral semiconductors can be used in optoelectronic devices that combine chiral optical and electronic properties: chiroptoelectronics. Their selectivity in absorbing left- or right-handed circularly polarised light (CPL)—circular dichroism—makes them promising candidate active materials for applications such as CP photodetectors. The latter could represent a breakthrough in the fields of remote sensing, optical imaging and communication. Although CHPs have great potential, the field is still in its infancy and many fundamental questions remain unanswered. The aim of this project is to conduct a systematic combined computational-experimental study of CHPs in order to determine structure-property relationships. These can be used in rational material design aimed at applications in chiroptoelectronics.
