Metal halide perovskites have emerged as a highly promising class of semiconductors for optoelectronic applications due to their exceptional light absorption, tunable emission, and efficient charge transport. These cost-effective materials have demonstrated an unprecedented rise in solar power conversion efficiency, reaching 28% within a decade, outpacing conventional silicon photovoltaics. However, fundamental insights into their intrinsic photophysical properties remain incomplete, yet are crucial for further performance enhancements. Additionally, while the impressive efficiency of novel perovskite materials is often emphasized, their long-term stability is equally vital for practical implementation.[1]
I will present the development of perovskite systems with diverse compositions, structures, and morphologies using various synthesis strategies. By employing advanced spectroscopic techniques, we elucidate the interplay between crystalline structure and charge carrier dynamics that dictate their optoelectronic performance.[2,3] Additionally, photoluminescence (PL) microscopy imaging is being exploited correlating materials’ photochemistry and intrinsic defects to optoelectronic device performance, providing direct insight into their function in real-world applications.[4,5] I will demonstrate how chemical micro-engineering can optimize perovskite stability and functionality, with a focus on improving X-ray detection performance.[6,7] Finally, I will present strategies for fabricating high-quality photoactive layers, including controlled film deposition, as critical components for next-generation stable optoelectronics.

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.
