Halide perovskites have become extremely competitive optoelectronic materials because of their high sunlight-harvesting efficiency and notable charge carrier generation/transfer capabilities. These features have been recognized as the key factors for enhancing photoconversion efficiencies in solar photovoltaic devices. Furthermore, their fascinating photoluminescence quantum yield (PLQY) especially in the case of colloidal nanocrystals, induced by a low nonradiative carrier recombination effect, can explain the expansion of their applicability in the wide optoelectronic field. The outstanding PLQY of perovskite nanocrystals is the clear evidence of the significant reduction of non-radiative recombination pathways. Consequently, after photoexcitation, these systems present a pool of photoexcited carriers whose extra energy can be used in an efficient radiative emission or taken advantage of in different ways, such as providing work in solar cells or driving diverse chemical reactions. Here, we shown the application of inorganic halide perovskite nanocrystals in the photocatalytical and photoelectrochemical degradation of Organic compounds, highlighting the potentiality to drive both oxidation and reduction reactions.
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.
