Hybrid halide-perovskites are considered a material with high potential in optoelectronics, especially for light-emitting diodes and solar cells. Perovskite-based solar cells (PSCs) are a promising substitute for commercially used silicon solar cells. Nowadays, the power conversion efficiency of PSCs reaches over 25 % [1]. However, further increase of the PSCs performance is limited by defects located at the layer interfaces and grain boundaries in the case of widely used polycrystalline thin films [2, 3]. Understanding and controlling the formation and evolution of perovskite phases is critical to reducing trap state density, thereby enhancing solar cell efficiency. The in situ studies have shown their significance in revealing the pathways and intermediary mechanisms that affect the resulting properties of the final PSCs.
In this work, we show simultaneous measurement of in situ grazing-incidence wide-angle X-ray scattering (GIWAXS) and photoluminescence (PL) to study the structural and optoelectronic properties of perovskite films during their formation. We used these in situ techniques for perovskite deposited by various methods, such as spin-coating (in a nitrogen atmosphere), chemical vapor deposition, and vacuum deposition. Despite different formation conditions, all perovskite layers exhibit the non-monotonous character of the PL intensity with initial PL increase and subsequent quenching, indicating the defective state formation correlated with the crystalline structure changes observed by GIWAXS. These studies contributed to developing passivation and additive strategies to improve the films' structural, morphological, and optoelectronic properties and move beyond spin-coating with scalable techniques.

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.
