Halide perovskites have rapidly emerged as a leading class of semiconductors for low-cost, high-efficiency optoelectronic technologies. However, their solution-based synthesis inherently produces a rich landscape of micro- and nanoscale inhomogeneities whose influence on device performance and long-term reliability remains insufficiently understood.
In this talk, I will present our recent efforts to unravel how structural motifs, chemical composition, and local photophysical behaviour are interconnected at the nanoscale, leveraging state-of-the-art multimodal imaging methods. We will show how synchrotron nanoprobe and optical spectroscopic methods, when correlated at the nanoscale, can explain the compromise between high-performing, defect-tolerant perovskite devices and irreversible degradation.[1,2] We will comment on the implications of these findings for the optical properties of halide perovskites, and how we can use them for the design of LEDs and photodetectors with new functionalities,[3,4] highlighting emerging opportunities for tailoring emission pathways, controlling carrier dynamics, and engineering stability through rational nanoscale design principles.
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.
