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.
