During the last decades, great attention has been devoted to organic-inorganic hybrid perovskites (OIHP) due to their special structures and important optical and optoelectronic properties. Since 2009, OIHP represented an exciting new class of low-cost solar absorber materials which have revolutionized the photovoltaic landscape by the exceptional growth of their power conversion efficiency from 3.8 % to more than 22 %1,2 in less than ten years. Moreover, their 2D counterparts exhibit strong photoluminescence, even at room temperature, making them promising candidates for the design of organic-inorganic light emitting diodes (OILED).3 Recently, we have observed a strong white-light emission, even at room temperature, in the 2D lead bromide based-OIHP, under UV irradiation.4 The maximum photoluminescence quantum efficiency (PLQE) of this very broad (~ 660 meV) emission was observed around 100K. Later on, we succeeded to partially control the chromaticity of the emission with the choice of halogen and metal.5 The same phenomenon was observed just before by Dohner et al. in some 2D (100)-oriented OIHP and a stable PLQE of 9 % has been measured, even after three months of continuous irradiation.6,7 Our optical and structural investigations suggested that this white-light emission results from self-trapped carriers in a deformable lattice due to the presence a strong electron−phonon coupling. Since these pioneering works, several research groups started exploring deeply this new phenomenon,7-11 which further confirms the great interest of these low-cost single-component white-light emitters in solid state lighting applications.

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.
