Over the last decade, metal halide perovskite materials have ushered in a new era for next-generation optoelectronics, primarily in photovoltaic and lighting applications. 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 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 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 light emitting diodes (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 CO reduction will also be presented.

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. Galian received her Ph.D in Chemistry at the National University of Cordoba, Argentina in 2001. Then, she was a postdoc researcher at the Polythecnic University of Valencia, University of Valencia and University of Ottawa. During those years, she has studied photosensibilization processes by aromatic ketones using laser flash photolysis techniques and was involved in photonic crystal fiber/semiconductor nanocrystal interaction projects. In 2007, Dr. Galian came back to Spain with a Ramon y Cajal contract to study the surface chemistry of quantum dots and since 2017 she has a permanent position as Scientist Researcher at the University of Valencia. Her main interest is the design, synthesis and characterization of photoactive nanoparticles and multifunctional nanosystems for sensing, electroluminescent applications and photocatalysis.
