Multinary semiconconducting / hybrid materials like perovskites are usually deposited in wet-chemical or evaporation processes. Growth kinetics and reaction paths of these deposition methods generally exhibit a high degree of complexity and are influenced by effects such as diffusion, phase transitions and numerous chemical reactions. Due to this complexity, process optimization for these materials usually takes place in a very empirical instead of analytical, knowledge-based manner. Accordingly, the learning curve bears a great potential for further acceleration. Visualizing and modelling the effects underlying growth and deposition is key for an analytical way of optimization, as it provides the base data for modelling and obtaining in-depth understanding of the processes. At the same time, such data, if obtained “in-situ”, can also be used for controlling and automating the deposition process. Optical metrology methods like in-situ reflectance spectroscopy are ideally suited for these purposes. They are directly linked with the absorption properties of the material, which again directly depend on composition, crystallinity and roughness, and they do not influence the deposition process. In order to obtain the best possible in-situ data for a given process, the metrology system needs to be engineered for optimum performance, (choosing the appropriate optical design, wavelength range, resolution and acquisition speed). In this talk we will demonstrate how, with an appropriately designed system, in-situ metrology can be used for visualizing and analyzing the growth kinetics of wet-chemical and evaporation processes.
Comment: This is supposed to be a sponsor talk
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.
