Different series of layered perovskites, based on lead and tin tetrahalide sheets intercalated by organic cations, are modeled with ab initio techniques. The structures are optimized at the DFT level, with inclusion of dispersion contributions, in several symmetry groups or without symmetry constraints.
The electronic properties (mainly, band structures and gaps) are computed at the state-of-the-art level with inclusion of spin-orbit-coupling (SOC) and post-DFT (GW) corrections.
A number of structure/properties relationships are discussed: in particular, we describe how the nature of the intercalated cations influences the perovskite band gap either directly or indirectly (through geometrical changes, e.g. to the interlayer distance).
Then we can sketch what combination of inorganic and organic counterparts can be used to select the desired electronic properties.
For photovoltaic applications, the computed band gaps of these layered systems are often too large. However, some of the modeled systems exhibit smaller gaps, sometimes as low as 1.4 eV, due to the electronic effects of suitable doubly charged cations: we discuss such effects, as well as effective molecular descriptors to predict the formation of such low band gap perovskites.
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.
