Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV22)
Publication date: 20th April 2022
Inorganic metal-halide perovskite solar cells have attracted wide interest throughout the field. They possess a number of attractive features however, an increased stability to temperature, moisture and air, compared to organo-metal halide perovskites, is an area warranting further investigation.
CsPbBr3 inorganic PSCs, with carbon electrodes, can achieve impressive Voc values, reaching over 1.23 V, the standard potential for the oxidation of H2O. These PSCs have been encapsulated and placed in an aqueous electrolyte solution to achieve photoelectrochemical oxygen or hydrogen evolution. [1,2] In our work, we have encapsulated the PSCs using a commercially available graphite sheet, with a molecular Ir-based water oxidation catalyst (WOC) grafted onto the surface. [3]
We are investigating a number of possible approaches to improve water oxidation at the surface of the PSC. In particular, we have improved the encapsulation of the device, allowing for water oxidation to occur for over 140 h, producing currents well above 1 mA. Furthermore, alternative strategies for increasing the amount of the WOC bound to the surface of the photoanode have been studied, in order to increase the number of active sites available for water oxidation.
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.
