The climate crisis is one of the most pressing challenges of our time. Global and coordinated action to reduce greenhouse gas emissions and mitigate their impacts is indispensable. Proposed solutions to address this crisis include the adoption of renewable energy, increased energy efficiency, reforestation, and the use of innovative technologies. In the technology sector, photocatalysis is attracting growing interest, fueling intense research into new materials.1 In our study, we examined the photocatalytic activity of heterojunctions between Bi2WO6 and Cs3(Bi1-xSbx)2Br9. Bi2WO6 is a widely recognized graphitic material in the field of photocatalysis, while perovskites, known for their excellent tunability, prove to be outstanding co-catalysts.2,3 Lead-free inorganic perovskites have been the subject of numerous studies for years.4,5 Of particular interest is the introduction of different metals into the B-site, introducing a high entropy approach which is still in its infancy.6 In our study, we analyzed how the structural and optical properties change with increasing doping rates. The formation of a heterojunction between the two materials could create a more complex charge carrier transport pattern than with single materials, increasing their lifetime and thus improving photocatalytic results.7 The heterojunction is facilitated by the innovative in-situ synthesis adopted, in which perovskite is formed within a solvent in which Bi2WO6 has been dispersed. The aim of the project is the photocatalytic splitting of water and CO2, underlining the importance of property-structure relationships also in the photocatalytic field. The project aims to highlight the differences in various set-ups, whether liquid-liquid or gas-solid. The discovery of new materials and the acquisition of new knowledge about photocatalysts are key to the development of advanced technologies for CO2 reduction. Photocatalytic methane evolution paves the way for a circular ‘waste to fuel’ economy in which waste molecules such as CO2 regain value.
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.
