Organic-Inorganic Hybrid Perovskites (OIHPs) have emerged as remarkable alternative to the conventional candidates in the renewable energy industry due to its exceptional opto-electronic properties. Recently, OIHPs have disrupted the field of new optoelectronic devices beyond just solar cells and LEDs. These include supercapacitors, electrochemical devices for water splitting, memory devices, energy storage devices, detectors, etc. However, the ion migration in this material has always been the topic of discussion among the scientific community. This ion migration in OIHPs leads to adverse consequences such as interfacial reactions, material decomposition and phase segregation affecting the stability and performance of these devices. External stimuli such as oxygen, moisture, elevated temperature, light illumination, and external bias impairs the condition to a significant extent. Numerous studies have been performed to decipher the nature of ion migration and controlling its behavior according to the device requirements. Still the complete picture is vague.
Exploring the recent advances in the understanding of the kinetics of ion migration in OIHP based devices is one of the goals of this research topic. Advanced small perturbation frequency domain techniques such as impedance spectroscopy, intensity modulated photocurrent/photovoltage spectroscopy have provided useful insight on the nature of ion migration lately. In addition, the prospects, and potential challenges in utilizing OIHPs in optoelectronic devices other than solar cells and LEDs will be investigated. Many devices such as memristors, photodetectors, supercapacitors, FETs have exploited OIHPs for their extraordinary optoelectronic properties. The strategies employed for tuning the ion migration in these optoelectronic devices to reduce material degradation and achieve higher stability while maintaining the performance can be generalized. Numerous approaches have been reported for the inhibition of ion migration in OIHP devices to achieve high performance. These include structural and dimensional modification in bulk perovskite, interface engineering between perovskite layer and transport layer, transport layer engineering and introducing new transport layers. However, the search for the perfect structure is still proceeding. The latest advances in all these aspects of ion migration in OIHP based optoelectronic devices will be addressed in this Research Topic.
Topics of interest include, but are not limited to, the following:
- Ion migration in organic-inorganic hybrid perovskites
- Advance spectroscopy techniques such as impedance spectroscopy, intensity modulated photocurrent/photovoltage spectroscopy, transient photocurrent/photovoltage spectroscopy
- Hybrid perovskite based optoelectronic devices such as solar cells, LEDs, and photodetectors
- Optoelectronic materials and device applications
