Halide perovskite (HaP) materials have attracted great scientific interest in the past decade, which is in part because of their unique combination of properties. These systems show various fascinating physical properties revolving around their apparent electronic-structure and optical characteristics, which are concurrent with finite-temperature vibrational properties that are very unusual for technologically useful semiconductors and demand explanation. Here, I will present our most recent theoretical findings obtained by molecular dynamics based on density-functional theory for the all-inorganic, cubic CsPbBr3. It will be shown that motions of neighboring Cs-Br atoms interlock such that most likely Cs-Br distances are significantly shorter than what is inferred from an ideal cubic structure. The dynamic Cs-Br coupling coincides with shallow potential wells for anharmonic Br motions occurring within locally and dynamically disordered energy landscapes. These Br motions are found to occur preferentially perpendicular to the Pb-Br-Pb bonding axis, which leads to a rapid rise in the joint density of states. This is a favorable feature for photovoltaics, since it implies sharp optical absorption profiles.
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.
