Photoelectrochemical and photocatalytic conversion of water and carbon dioxide using solar energy offers a clean solution to the world energy requirements of a sustainable future. Achieving its full potential depends on developing inexpensive photoelectrodes and photocatalysts that can efficiently absorb solar light and drive the photoinduced charges to react with water and carbon dioxide. In this talk, I will present recent developments we have achieved in the group in the preparation of inexpensive photoanodes, photocathodes and photocatalyst composites. For example, we have achieved nanostructured BiVO4 functionalized with bismuthene and NiFeOx that influence surface states and boost 6 times their photocurrent performance, as well as BiVO4 with Ni and Co phosphide co-catalysts that offer a useful series of samples to understand semiconductor-electrocatalyst synergies. We have also achieved halide perovskites CsPbBr3 photoanodes protected with printed carbon layers and graphite sheets and functionalized with NiFeOx water-oxidation electrocatalyst, achieving photoanodes of low onset potential of +0.4 V vs. RHE and photocurrents around 8 mA cm-2 at 1.23 V vs. RHE for water oxidation. These, moreover, achieve operational stabilities for oxygen evolution above 100 h, inexpensively extended to weeks by replacement of the graphite protection. We will also briefly present photocathodes made of oxide perovskites and composites of halide perovskites, such as Cs2AgBiBr3/bismuthene and Cs3Bi2Br9/g-C3N4, for their use in the photocatalytic reduction of CO2. An extended characterization helps us relate their physical and charge-transfer properties to their performance, guiding us in their rational design for their optimization and future application.
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.
