When aiming at maximizing performance of photoelectrochemical and electrochemical devices, the ability to tailor-make material platforms with tunable morphologies in an unrestricted compositional range is critical for achieving optimal design specifications, as well as providing understanding of the sensitivities of performance parameters to different compositional and structural parameters.
Colloidal synthesis is a surfactant-assisted approach that has proven to be one of the most powerful solution-based processes to tailor the size, the shape and the composition of nanocrstalline materials. This superiro control afforded by colloidal chemistry, combined with solution processability and rich surface chemistry, has provided access to modular inorganic nanocomposites with unprecedented tunability. Nonetheless, the full potential of colloidal chemistry has not yet been fully explored for solar-to-chemical energy conversion.
This presentation highlights how colloidal chemistry can aid to construct materials for storing energy in chemical bonds. Specifically, our recent studies on complex metal oxide light absorbers to drive water oxidation and on copper nanocubes to carry out electrochemical CO2 reduction will be discussed.[1-4]

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.
