Efficient artificial photosynthesis systems are currently developed for photoelectrochemical (PEC) water oxidation while simultaneously recycling CO2 and generating hydrogen as a solar fuel for storable renewable energy. These systems comprise e.g., integrated semiconductor-electrocatalyst devices which offer several benefits such as high system tunability with respect to the electrocatalyst integration and a directly controllable electron flux for the electrocatalytic process through the adjustability of incoming irradiation. These characteristics could also represent a significant advantage for electrocatalytic dinitrogen reduction, although PEC devices remain little explored for this reaction. Here, we will discuss recent developments in fabricating and designing integrated semiconductor-electrocatalyst systems for small molecule activation - in particular dinitrogen fixation - by focusing on the design principles of the electrocatalyst.
In a second part, we will discuss the possbility of specially engineering the electrocatalyst nanotopography for enhanced gas bubble detachment - a common obstacle in gas producing solar fuel devices, but also in traditional electrolyser systems. Reporting on experimental results obtained from the Bremen Drop Tower where microgravity can be achieved in 9.3 s of free fall, we outline possibilities for designing electrocatalytically active surfaces for efficient gas bubble detachment even in the absence of buoyancy, resulting in significant device performances increases and lower overall energy inputs.
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.
