Photocatalytic hydrogen production using 2D Ruddlesden-Popper tin iodide perovskites emerges as a promising approach for sustainable energy conversion. However, a key challenge associated with these materials is their susceptibility to degradation due to the oxidation of tin and iodide. In this study, microcrystals of 4-fluorophenethylammonium tin iodide perovskite were synthesized in a mixture of hydroiodic acid (HI) and water, demonstrating long-term photostability and robust photocatalytic hydrogen production via HI splitting. Intermittent light irradiation was found to enhance hydrogen evolution by promoting more efficient charge separation and reducing the accumulation of trapped charge carriers that would otherwise lead to recombination. Notably, reused samples exhibited improved photocatalytic performance over time. Furthermore, degraded samples could be easily regenerated through a simple chemical treatment, restoring their hydrogen production capability. In addition, the use of Sn-based perovskite solar cells as photocathodes in aquous solution for hydrogen generation will be also reported, highlighting the interest of Pb-free perovskites for photocatlytic applications.

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.
