Halide perovslkites are well known for their excellent optoelectronic properties that has enabled them to create record breaking performances in areas of solar harvesting, light emitting diodes and detectors. In this talk we will focuss on the ionic effects within this family of semiconductors which is normally as its weakness. The talk will cover our efforts to modulate and utilise the ionic properties of halide perovskites.
The significant ionic activity in these materials enables their use in memory devices, where the interplay between ionic and electronic transport gives rise to resistive switching behavior. These distinctive characteristics make halide perovskites highly promising for neuromorphic applications. Their strong light absorption and coupled ionic–electronic transport allow them to be stimulated by both electrical and optical inputs. In this presentation, I will discuss various approaches to modulate the material compositions, interfaces to tailor memristive behavior in a wide variety of architectures including memristive PV devices as well as perovskite-based LEDs with integrated memory functions. These devices can emulate a wide variety of functions such as human visual processing, enabling functions such as contrast enhancement, feature extraction, and other forms of sensory pre-processing. Finally, I will also touch on how perovskite-based memory devices can be engineered to emulate artificial neurons, paving the way for highly integrated and multifunctional neuromorphic architectures.
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.
