Having a theoretical 18.5% solar-to-hydrogen efficiency, LaTaON2 is anticipated to be an efficient photoanode material. However, LaTaON2 has been reported to exhibit very low solar photocurrent of 0.15 mA cm-2 at 1.6 VRHE in the literature. In this study, the solar photocurrent of LaTaON2 achieves a record value of 2.1 mA cm-2 at 1.6 VRHE, an order of magnitude higher than the previously-reported value. This dramatic enhancement is ascribed to hybrid structure of nanoparticles and porous microparticles, as well as CoOx modification. The hybrid structure may not only block the back reaction on the conductive substrates greatly, but also reduce the transfer distance of the photoinduced holes to reaction sites for water oxidation. On the other hand, the CoOx nanospheres, recrystallizing from the as-deposited amorphous layer after annealed under NH3, are observed by HRTEM (High Resolution Transmission Electron Microscopy). These CoOx nanospheres on LaTaON2 particles facilitate the formation of the Schottky nano-junctions accelerating the hole transport, thereby leading to ca. 260% increase in the photocurrent at 1.6 VRHE.
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.
