As metal halide perovskites approach technological maturity, the research is now shifting from record-breaking efficiencies toward stability, scalability, and environmental sustainability. While lead-based perovskites currently hold the highest performance in photovoltaics, lead-free alternatives are rapidly emerging, offering not only reduced toxicity but also distinctive optoelectronic properties. In this talk, I will present recent advances spanning from tin-based three-dimensional perovskites to bismuth halide-based compositions, highlighting how compositional and structural diversity can be exploited to target a broad range of optoelectronic applications. Particular attention will be devoted to the relationship between composition, defect physics, and stability. Tin-based perovskites enable narrower bandgaps suitable for infrared absorption and tandem applications, while low-dimensional bismuth-based compounds exhibit broadband visible emission arising from their localized electronic states. These features open new opportunities that extend beyond the capabilities of conventional lead-based materials. Beyond materials design, the talk will also emphasize the development of scalable and green processing strategies. I will discuss approaches ranging from mechanochemical synthesis of perovskite powders to the deposition of thin films via slot-die coating, demonstrating pathways toward industrially relevant fabrication while avoiding the use of toxic solvents. By integrating advances in materials chemistry with sustainable manufacturing, this talk reviews the development of stable, scalable, and environmentally friendly perovskite technologies.
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.
