In recent years, metal halide perovskites (PVSKs) have attracted significant attention due to their outstanding opto-electronic properties, low cost, and simple processing. However, the performance of perovskite opto-electronic devices is limited by defects causing the undesirable recombination of charge carriers within the PVSK layers. Therefore, it is necessary to understand the process of perovskite nucleation and formation to challenge the boundaries of their high efficiency. Here, we present a study of both opto-electronic properties and the structure of PVSK thin films during vacuum co-deposition of methylammonium lead iodide (MAPbI3). For this work, we employ a simultaneous measurement of in situ grazing-incidence wide and small-angle X-ray scattering (GIWAXS and GISAXS) and photoluminescence (PL). The non-monotonous character of the PL evolution throughout growth with initial PL emission increase and subsequent decay reveals the formation of defective states correlated to crystalline structure and morphology changes along with the grain formation observed by GIWAXS and GISAXS. This combined real-time study might be a valuable tool for the selection of additives and materials in targeted defect passivation.
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.
