Photon induced Spintronics on Hybrid Organic-inorganic Perovskites: Effect of Rashba Spin-Orbit Coupling

Project description

Probing the subtle spin behaviour of hybrid perovskites

Perovskites offer great promise for further increasing the efficiency of solar modules in the future. Owing to their high carrier mobility, excellent semiconducting properties and extremely high energy conversion efficiency, organic–inorganic trihalide perovskites have recently attracted a great deal of attention. Funded by the Marie Skłodowska-Curie Actions programme, the SpinPVK project aims to thoroughly study the characteristic electron spin behaviour of these hybrid materials. Overall, the project will develop spintronic devices based on these materials and investigate spin-related properties such as the spin–orbit coupling, the Stark effect, magneto-optical effects, polarisation effects and complex light emission properties.


In the Last few years, hybrid organic-inorganic trihalide perovskite (HOIP) solar cells an imperative and motivating research field and this is an interesting multifunction material owing to their high carrier mobility, semiconducting properties, and extremely high performance in solar cells (achieved solar power conversion efficiency is >25%). On the other hand, a numerous theoretical and experimental research were done and going based on perovskite materials. But, till the perovskite materials is a promising material for further development in photovoltaics and optoelectronics devices. However, beyond the photovoltaic applications, HOIP’s electron spin characteristic behaviour have not been studied in detail and the reports are very limited. In this SpinPVK project, to demonstrate the effect of spin states in perovskite materials photovoltaic and optoelectronic devices, due to the spin-orbit coupling (SOC). Also, to study the photon induced spin-polarized carrier injection into HOIP’s for spin light emitting diode and spin-valve devices. we will switch the photoexcited charge carrier polarization from linear to circular polarization by the effect spin induced band shifting, which will be increase the photocurrent and photovoltage in HOIPs photovoltaics. In addition, we will validate the influence of perpendicular magnetic field on HOIP by photon induced spin orientation and long life time photocarrier for high efficiency perovskite solar cells (PSCs).
Overall, this SpinPVK project aims to develop and fabrication of HOIP based spintronic devices and which will be delivered in-depth knowledge about spin-related properties such as SOC, Stark effect, magneto-optical effect, polarized light-related effect, complex light emission and spin/photon induced photovoltaics. Also, this project will be proved to overcome the stability issues in HOIPs for pav way of commercialization.
