Perovskite nanocrystals (PNCs) are promissory materials in optoelectronics due to improved light harvesting, photocarrier generation and the ease for tuning their optical properties, by varying their particle size and halide composition.[1] These characteristics have opened the door to interesting applications such as photo(electro)catalysis for carrying out oxidation/reduction reactions more efficiently.[2] However, there is a scarce in the state-of-the-art about the photo(electro)chemical (PEC) properties of these materials in form of electrodes for establishing their oxidizing/reducing power, also considering that the photocatalytic (PC) activity of PNCs mainly depends on the surface chemical environment formed during their synthesis. In this contribution, we show the ability of PNCs to perform photo(electro)catalytic degradation of targeted organic molecules as a proof-of-concept, and we also deduce how the purification of PbX2 precursors as a defect-engineering strategy influences on their PC properties. Then, we demonstrate that the use of different carrier transporting layers impacts on the PEC behavior of PNCs based photomaterials, fabricating selective photoelectrodes to perform oxidation/reduction reactions. Lastly, we address to lead-free PNCs with high potentiality for solar-driven chemical 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.
