Halide perovskites have significantly transformed the field of optoelectronics, enabling substantial advances in established technologies such as solar cells and light-emitting diodes (LEDs), as well as in emerging devices including memristors. A defining characteristic of these materials is their propensity for ionic migration. Although ion transport is typically regarded as a detrimental effect that contributes to the performance degradation of solar cells and LEDs, it is fundamentally the mechanism that facilitates resistive switching in memristive devices. Consequently, a comprehensive understanding of ionic transport and strategies for its precise control are critical for the rational design of high-performance devices.
This presentation will examine in detail the mechanisms of ionic migration in halide perovskites and outline approaches for modulating this behavior. To expedite progress in this area, high-throughput characterization methodologies have been developed to systematically evaluate ionic transport, thereby enabling precise control over ion dynamics and the realization of functional memristors across diverse applications. A range of device architectures and operational mechanisms—including switchable photovoltaics, photovoltaics exhibiting persistent photovoltage, bipolar photoconductor switching, color-tunable LEDs, and self-rectifying memristors—will be discussed as platforms for achieving novel functionalities. These advances further enable the development of sophisticated hardware security technologies, such as Physical Unclonable Functions (PUFs), as well as advanced neuromorphic systems, including in-sensor and reservoir computing.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
