Over the last decade, halide perovskite materials have ushered in a new era for next-generation optoelectronics. However, widespread concerns related to PB toxicity and material and device stability have spawned efforts to explore alternative PB-free perovskite and perovskite-inspired materials guided by a combination of theoretical prediction and experimental trials. Depending on the chemical composition, processing routes, and structural and electronic dimensionality, these lead-free perovskites exhibit distinctive properties. This symposium will discuss the exploration of novel lead-free alternatives and their unique structure-composition-property relationship. Our discourse will cover the current state-of-the-art in the performance and stability of lead-free perovskite solar cells and LEDs. Parallelly, we will focus on the notable strides demonstrated in the area of lasers and photo- and X-ray detectors where the performance of lead-free perovskite devices is comparable or even superior to their lead-based counterparts. Finally, the recent application of these novel materials to indoor photovoltaics (PV), transistors, thermoelectrics, water splitting, and CO2 reduction will also be presented. Implications on sustainability and toxicity twill be welcome. After the success of the 2025 and 2026 MATSUS Spring Meetings, this topic deserved continuation along time to show the novelties in the field and consolidate as a reference of MATSUS Spring Meeting.

Iván Mora-Seró (1974, M. Sc. Physics 1997, Ph. D. Physics 2004) is researcher at Universitat Jaume I de Castelló (Spain). His research during the Ph.D. at Universitat de València (Spain) was centered in the crystal growth of semiconductors II-VI with narrow gap. On February 2002 he joined the University Jaume I. From this date until nowadays his research work has been developed in: electronic transport in nanostructured devices, photovoltaics, photocatalysis, making both experimental and theoretical work. Currently he is associate professor at University Jaume I and he is Principal Researcher (Research Division F4) of the Institute of Advanced Materials (INAM). Recent research activity was focused on new concepts for photovoltaic conversion and light emission based on nanoscaled devices and semiconductor materials following two mean lines: quantum dot solar cells with especial attention to sensitized devices and lead halide perovskite solar cells and LEDs, been this last line probably the current hottest topic in the development of new solar cells.
Dr Luis Lanzetta is a Postdoctoral Fellow at King Abdullah University of Science and Technology (KAUST, KSA). He obtained his PhD in Chemistry at Imperial College London (UK) in 2020, where he focused on developing eco-friendly, tin-based perovskites for photovoltaic and light-emitting applications. His research focuses on next-generation materials for energy harvesting. Specifically, his expertise lies in the chemical degradation and stabilisation mechanisms of halide perovskite solar cells, aiming to provide design rules towards more efficient and stable technologies. He is additionally interested in molecular doping approaches for narrow-bandgap perovskites, as well as the spectroscopic and surface characterisation of this class of materials.

Born on January 7, 1988.
During my undergraduate studies I had the chance to carry out two short-term research projects on nanomaterials at Tohoku University (Japan; 2010) and Université de Sherbrooke (Canada; 2011). I then obtained my Master of Science in Nanoscale Engineering and my PhD on Materials Science from Ecole Centrale de Lyon (France; 2011 and 2014). From 2015 until December 2017 I was a post-doctoral researcher in the Nanochemistry Department of the Istituto Italiano di Tecnologia of Genova (Italy). In 2017 I was awarded a "Marie Sklodowska Curie Actions" fellowship to develop my project PerovSAMs in the Instituto de Ciencia Molecular (ICMol) at the Universidad de Valencia, where I continued working with a "Juan de la Cierva incorporación" fellowship until 2021. In 2022 I joined Universidad Politécnica de Cartagena (UPCT) as a "Ramón y Cajal" fellow.
Throughout my career I have worked in the fields of materials' chemistry, colloidal inorganic nanocrystals, surface analysis and halide perovskites' optoelectronic devices among others. My publications and bibliometric indicators can be found elsewhere (e.g. Google Scholar or Scopus).
Aside from research I have also maintained a teaching activity throughout my career with lectures and practical courses in chemistry and chemical engineering at undergraduate level (Ecole Centrale de Lyon, 2011-2014 and 2020-2021; Universidad de Valencia and Universidad Politécnica de Valencia, 2018-2019; Universidad Politécnica de Cartagena, 2022-present) as well as specific courses in surface analysis techniques for PhD students (Istituto Italiano di Tecnologia; 2015-2017). I have supervised one Master of Science thesis, one PhD thesis and I currently supervise two other PhD theses.
Eventually, I am also involved in the "Federación de Jóvenes Investigadores" where we strive for a better spanish scientific and academic system, especially fighting against the precarity of young or junior researchers.
