Tin and lead perovskite solar cells have proven to have optical properties ideal for achieving maximum efficiency. However, their large-scale use has been hindered by stability issues on their surfaces, such as oxidation, defects that make them vulnerable, or chemical mismatches in the charge transport layers.
Self-assembled monolayers (SAMs) are ordered structures of molecules that spontaneously form on solid surfaces through specific chemical interactions. SAMs could serve as alternative transport layers for these types of solar cells, addressing the surface-related issues. The goal of Dr. Luis Lanzetta's SAMper project is to design chemically intelligent devices with perovskite healing capabilities and the ability to neutralize oxidants, to create ultra-stable and highly efficient cells.
Dr. Luis Lanzetta is a specialist in materials chemistry and the synthesis and characterization of tin or tin-lead perovskites. His expertise focuses on the degradation mechanisms and stabilization of halide perovskite solar cells, aiming to achieve more efficient and stable technologies. He completed his PhD in Chemistry at Imperial College London (UK) and has been a postdoctoral researcher at KAUST (Saudi Arabia).
For the study, Dr. Luis Lanzetta will join the Advanced Semiconductors Group at the Institute of Advanced Materials of the Universitat Jaume I, directed by Professor Iván Mora Seró. This group has a strong track record in the development and advanced characterization of perovskite solar cells, focusing on identifying the physical processes that govern their operation and developing additives to improve their performance and stability.
The final phase of the project, which involves outdoor testing over extended periods, will take place at the École Polytechnique Fédérale de Lausanne in collaboration with Dr. Sánchez-Alonso and under the supervision of Professor Sivula. Their environmental conditions, with an altitude of more than 1,800 meters, will provide high ultraviolet irradiance and variable temperatures to test the operational stability and efficiency of the cells under harsh environmental conditions.
