Perovskite type materials exhibit high absorption coefficient, and possibility of band gap tuning, what makes them a good option for solar cell application. One of the most important advantages of perovskite absorbers is the simplicity of preparation within low costs compared to inorganic state-of-the-art semiconductors. However, successful application is often limited by crystalline properties of materials due to solution processing. Thus, devices based on such hybrid compounds usually suffer from morphology issues.
In our work we propose new approach of morphology improvement based on rapid melting procedure. This simple treatment allows obtaining up to micrometer size grains within 1 minute. The procedure was optimized in time and temperature for gradual grain size growth in a broad range. Since the procedure is a post treatment it can be used substrate and/or sample-independent.
Changes of the crystalline state of treated samples were monitored with PL spectroscopy by increase of signal intensity and redshift. Moreover, melted samples were analyzed via XRD measurement to insure presence of the perovskite structure in the post-treated films. Consequently, application of the rapid melting technique gives a possibility to enhance the crystallinity of perovskite thin-films in precisely controlled conditions, that can be applied on industrial scale.
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.
