The performance of semiconducting materials as photoanodes is continually optimised overtime. With the aid of nanostructuring, noteworthy performance enhancements for the water oxidation reaction are obtained when coupled with electrocatalysts such as FeOOH/NiOOH and Co-Fe Prussian Blue.1,2 In the longstanding compromise between the light penetration depth and charge diffusion lengths, nanostructuring provides an effective tool. However, it is not often efficacious unless coupled with co-catalyst or in presence of hole scavengers. This highlights the presence of significant surface recombination that is especially critical for kinetically demanding reactions such as the four hole oxidation of water, requiring the accumulation of holes on the surface.
In this talk, we will discuss the structure performance relationship between densely packed and mesoporous structures of bismuth vanadate alongside other n-type materials such as titania and hematite. Using techniques such as transient photocurrent measurements (TPC) and photo induced absorption spectroscopy (PIAS), we can directly probe the influence of porosity and increased surface area on electron transport and photo-catalysis.

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.
