Metal halide perovskites have been widely studied in the fields of optoelectronics, due to their tunable optical and electronic properties. The typical structure, ABX3, involves a large monovalent cation (A) like Cesium or Rubidium, a divalent metal cation (B) (where Pb stands out for the optical properties)[1], and a halogen (X).
A relatively novel application involves the use of dimensionally reduced perovskite nanocrystals (PNCs) in photocatalysis and photoelectrochemistry, where H2 evolution[2] and CO2 reduction[3] have been already demonstrated.
Due to the Pb toxicity and limited stability to standard environmental conditions, research is now focusing on developing lead-free halide perovskites, like the Bi-based vacancy-ordered perovskites (A3B2X9) or the double perovskites (A2B(I)B(III)X6), where Pb2+ is replaced by a combination of +1 and +3 cations (such as Ag+ and Bi3+).
Our work is focusing on the synthesis and characterization of bismuth-based PNCs, where multiple candidates are being studied, such as the Cs3Bi2X9 and Cs2AgBiX6 (X=Cl, Br,I) PNCs, improving their optical properties through metal Ion doping. In addition, we aim at preparing hybrid heterostructures with other low-dimensional materials, such as graphene-based materials, carbon nanotubes, 2D carbon nitrides and 2D transition metal dichalcogenides employing covalent and non-covalent hybridization methods, in order to improve stability and activity in photo(electro)catalysis.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
