Over the last decade, halide perovskite materials have ushered in a new era for next-generation optoelectronics. However, widespread concerns related to lead toxicity and material and device stability have spawned efforts to explore alternative lead-free perovskite and perovskite-inspired materials. Depending on the chemical composition, processing routes, and structural and electronic dimensionality, these lead-free perovskites exhibit distinctive properties when compared to their lead-based analogues. This symposium will bring together the community to 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 as well as brainstorm on the outstanding challenges that need to be tackled to improve these performance parameters significantly. 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, sustainability and life cycle assessment will also be presented.

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.
Spatially-resolved characterisation is crucial to understand micro- and nano-scale phenomena underpinning the operation of optoelectronic devices and guide their development. In the case of halide perovskites, both reversible (hysteresis / self-healing) and irreversible (degradation) instabilities provide additional challenges compared to more established optoelectronic materials. This symposium will focus on techniques using electron, optical and x-ray microscopy and spectroscopy, to unravel nanoscale and microscale properties and dynamics of perovskite materials (in films, bulk and nanocrystal form). It will also cover the use of multi-dimensional, hyperspectral and scanning electron diffraction approaches to maximise information retrieval and data interpretation.

Metal halide perovskites have emerged as versatile semiconductors with exceptional optoelectronic properties, driving advances across photovoltaics, light-emitting devices, photodetectors, and photoelectrochemical systems. However, their intrinsic and extrinsic instability remains a significant bottleneck toward large-scale deployment. Degradation under moisture, heat, light, oxygen, and bias, limits device performance and lifetime. These challenges affect both lead- and tin -based perovskites, and are critical across different device formats, small area cells and more abrupt in large-area modules. The symposium will address the latest developments in understanding and improving the stability of perovskite materials and devices. Topics will include intrinsic material stability via compositional and structural engineering, encapsulation strategies, interface passivation, additive engineering, and innovative device architectures (e.g., HTL/ETL-free, tandem, or flexible formats). Emphasis will also be placed on stability in photovoltaic applications, and others such as photoelectrochemical water splitting, radiation detection, and light emission. Contributions covering scalable fabrication methods, accelerated aging protocols, and reliability under operational conditions are encouraged. We welcome discussions encompassing both experimental and theoretical approaches, aiming to define robust pathways toward durable, high-performance perovskite-based technologies.

Ifan is a Professor in Electrochemistry at the Department of Materials at Imperial College: he leads the Interfacial Electrochemistry Group there and is also Atoms to Devices Research Area Lead at the Henry Royce Institute.
Ifan joined Imperial College in July 2017. Prior to Imperial, he was at the Department of Physics at the Technical University of Denmark (DTU); he was first employed as a postdoctoral researcher, then as assistant professor and finally as associate professor and leader of the Electrocatalysis Group there. In 2015, Massachusetts Institute of Technology (MIT) appointed Ifan as the Peabody Visiting Associate Professor. He taught and conducted research at the Department of Mechanical Engineering at MIT for a whole semester.
Ifan’s research aims to enable the large-scale electrochemical conversion of renewable energy to fuels and valuable chemicals and vice versa. Such processes will be critical in order to allow the increased uptake of renewable energy. His focus is on the catalyst at the electrode, i.e. the electrocatalyst. It turns out that the electrocatalyst material defines the efficiency of several important electrochemical processes, including:(i) electrolysis for the storage of renewable electricity — which is inherently intermittent — in the form of fuels, such as hydrogen or alcohols.(ii) fuel cells as a potentially zero emission source of power for automotive vehicles. (iii) the green synthesis of valuable chemicals, such as ammonia and H2O2. (iv) batteries, which tend to degrade by gas evolution at the electrode-electrolyte interface. Hence the reactions that need to be accelerated in electrolysers and fuel cells — such as CO2, CO, O2 and H2 evolution — are precisely those that need to be inhibited in batteries.
Ifan has discovered or co-discovered several new catalysts for the oxygen reduction reaction, which exhibited significant improvements in performance over the prior state-of-the-art. In particular, his research on hydrogen peroxide production led to the establishment of the spinout company, HP Now.
Ifan is the recipient of RSC's Geoffrey Barker Medal (2024), the RSC's John Jeyes Award (2021). He also currently holds an European Resarch Council Consolidator Grant (2021-2025). Since 2022, he has been a Clarivate Highly Cited Researcher.
The compositional versatility of halide perovskites makes this class of semiconductors highly attractive for multiple optoelectronic applications. Specifically, tin- and mixed tin-lead systems offer unique functionality due to their narrow bandgaps, enabling near-infrared (NIR) light absorption and emission. This property opens avenues for scalable, low-cost and efficient single-junction and all-perovskite tandem solar cells, as well as photodetectors and light-emitting diodes (LEDs) for NIR sensing and imaging.

Understanding the behavior of energy-related materials under realistic operating conditions is essential for the rational design of more efficient systems for energy conversion and storage. The chemical composition, oxidation states, and structural evolution at interfaces and in the bulk are all determined by the surrounding environment, which ultimately controls the material's functionality. However, capturing this information during operation remains highly challenging, as the harsh conditions required for many processes—such as high pressures, liquid electrolytes, or reactive gas atmospheres—are often incompatible with traditional analytical methods. Synchrotron-based X-ray techniques have become powerful, non-destructive tools to address this challenge, offering element-specific insights into electronic structure, oxidation states, and chemical speciation from bulk to surface. Despite their potential, applying these techniques under operando or in situ conditions, particularly in electrochemical or catalytic environments. In recent years, significant progress has been made toward adapting synchrotron methodologies to probe working systems under relevant conditions. This symposium will highlight recent advances in in situ and operando synchrotron X-ray techniques for the study of energy materials, including electrocatalysts, battery electrodes, and systems for hydrogen production and CO₂ conversion, among other. Emphasis will be placed on both methodological innovations and their application to technologically relevant processes, aiming to bridge the gap between materials characterization and functional understanding under working conditions.

Chemical and electrochemical doping are widely used tools for adjusting the charge-carrier density and work function of organic semiconductors, from small molecules to polymers. Thus, doping is critical for a wide range of organic electronic devices, from solar cells and transistors to thermoelectric generators. A variety of doping methods exists and understanding of the underlying chemistry is gradually emerging.

This symposium invites contributions on the precision synthesis and chemical control of colloidal nanocrystals. There is growing interest in the application of versatile nanocrystals, including metal halide perovskites, II-VI, III-V group nanocrystals and carbon dots, in emerging technologies such as solar cells, light-emitting diodes (LEDs), and photodetectors.

The future scalability of electrochemical technologies, from green hydrogen production to next-generation batteries, hinges on urgent breakthroughs in critical raw material (CRM) use reduction and ultimately substitution (e.g. given expected technology deployment levels). Current systems often depend on scarce elements and or elements that may with time become critical (e.g. Platinum Group Metals, rare earths, etc.), creating bottlenecks that threaten both technological advancement and global supply security. Overcoming these constraints demands radical rethinking that leads to rapid advances in improved materials utilisation and potential substitution without compromising performance. This symposium convenes leading experts at the frontier of these efforts, exploring disruptive approaches to address CRM challenges in the electrochemical devices needed in the energy transition and bring forward the generations of resilient, high-performance electrochemical technologies (free from CRM dependency).

Quantum engineering is a vital breeding ground for future key technologies, from quantum computing and energy-efficient
optoelectronics to medical applications. However, the search for suitable material platforms is lagging. Guidelines may be
performance-based, e.g., related to the efficiency and reliability of quantum-state preparation, transfer, and read-out. On the
other hand, a more widespread deployment of quantum technology may also need to consider aspects such as scalability,
tunability, integrability, versatility, or cost-efficiency. In this respect, halide perovskites and other metal halides of various
