Hydogen production by water splitting is the key technology to solve energy, resources, and environmental issues. The representative artificial photosynthetic reation is water splitting. A photoelectrochemical system is one of the candidates to achieve an efficient water splitting of an artificial photosynthesis. Although various potential photoelectrodes with visible light response have been developed, most of them require an external electric assistance to split water. Recently, fablication of a combined system with such photoelectrodes and solar cells has been extensively studied to overcome that issue. For example, a perovskite solar cell with low cost and high efficiency has attracted much attention. In the present study, we demonstrate solar water splitting upon fabricating a system with a Pt/SiC photocathode, a CoOx/BiVO4:Mo photoanode, and a pervskite solare cell. The Pt/SiC and CoOx/BiVO4:Mo photoelectrodes gave cathodic and anodic photocurrents under simulated sun light irradiation, respectively. The current-potential curve of the Pt/SiC photocathode intersected that of the CoOx/BiVO4 photoanode at around 0.8 VRHE. Therefore, solar water splitting was tested using the combined photoelectrochemical cell with and without a perovskite solar cell. The cell without a perovskite solar cell gave a certain photocurrent and about 1 V of the photovoltage. The photocurrent was further boosted by using a perovskite solar cell. Thus, we successfully fabricated the artificial photosynthetic system for solar water splitting using photoelectrodes and a perovskite solar cell.
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.
