Perovskites have recently established themselves in a large number of (opto)electronic devices far beyond solar cells, such as gas sensors, transistors, photodetectors and thermoelectrics. However, the low long-term stability of the vast majority of inorganic and hybrid 3D perovskites still represents the main obstacle preventing their commercialisation. One possible solution is low-dimensional perovskites which have been shown to exhibit higher stability and lower ion migration than their 3D counterparts. Additionally, charge confinement allows ZT to be empowered. Thermal conductivity is reduced by scattering of phonons in the low-dimensional lattice, and the Seebeck coefficient is increased and the thermopower reaches its highest value when energy levels are discrete. To ensure technological applications, low-cost deposition processes, such as spin-coating, must be optimized to obtain a) controlled film morphology (roughness, grain size, grain boundaries, defects), b) pure phases and c) orientation of the layered structures parallel to the substrate. We report on the structural study of thin films of two different 1D pseudo-perovskite materials, namely PRSH)PbX3 (X = Br, I) and (TMSO)PbI/Bi3. Combining complementary techniques, such as GIWAXS, Specular XRD, SEM, EDX and XPS, we could describe the crystalline phases, mosaicity and disorder in film systems and their dependence on the solvent used, the concentration of the precursors and the stoichiometry. Furthermore, the time, ultraviolet radiation and moisture stability of the thin films are reported and correlated with the deposition conditions.
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.
