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

Projektbeschreibung

Raffiniertes Spin-Verhalten der Hybrid-Perowskite unter Beobachtung

Perowskite sind potenziell gut geeignet, um in Zukunft den Solarmodulwirkungsgrad weiter zu steigern. Aufgrund ihrer hohen Ladungsträgermobilität, ihrer ausgezeichneten Halbleitereigenschaften und ihrer extrem hohen Energieumwandlungseffizienz haben die organisch-anorganischen Trihalogenid-Perowskite in letzter Zeit viel Aufmerksamkeit auf sich gezogen. Das im Rahmen der Marie-Skłodowska-Curie-Maßnahmen finanzierte Projekt SpinPVK verfolgt das Ziel, das charakteristische Elektronenspinverhalten dieser Hybridmaterialien eingehend zu untersuchen. Insgesamt wird das Projekt Spintronikbauelemente auf der Grundlage dieser Materialien entwickeln und mit dem Spin verbundene Eigenschaften wie die Spin-Bahn-Kopplung, den Stark-Effekt, magneto-optische Effekte, Polarisationseffekte und komplexe Lichtemissionseigenschaften erforschen.

Ziel

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.
