Halide Perovskites have emerged as a revolutionary class of semiconductors, garnering intensive interest due to their exceptional and tunable optoelectronic properties, including high photoluminescence quantum yield (PLQY), high carrier mobility, and bandgap tunability across the visible spectrum. This versatility is demonstrated across various morphologies, nanocrystals (NCs), powders, thin films, and large single crystals, each offering unique advantages for specific applications. However, the dual challenges of lead toxicity and long-term instability have hindered their widespread adoption. While lead-free tin (Sn) halide perovskites are the most promising alternative, their poor stability, particularly the rapid oxidation of Sn2+ has severely limited the performance and lifetime of all device architectures.
In this presentation, we demonstrate a significant leap forward in stabilizing Sn-based perovskites. We detail how a synergistic approach combining targeted additive engineering and controlled light soaking passivates critical defects, enhancing the material's intrinsic stability. This strategy leads to a remarkable improvement in the operational lifetime of our solar cells, and we dissect the underlying mechanisms that go beyond simply preventing oxidation, enhancing stability and photoconversion performance.
This presentation provides a comprehensive investigation into the controlled synthesis and advanced applications of Sn-Perovskites. We show examples of the synthesis of powder as precursors for thin film formation and for application in LEDs, we will also investigate chiral perovskites. Single crystals have been synthesized by hydrothermal methodology with a without confined space. Overall, this study highlights the structural and compositional engineering required to exploit the full potential of halide perovskites, from nanoscopic to macroscopic forms, as a fundamental material system poised to drive breakthroughs in efficient illumination, coherent light generation, and sustainable chemical synthesis.

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.
