Halide perovskite solar cells have revolutionized the photovoltaic field in the last decade, due to its direct bandgap and high absorption coefficient, with a benign defect physic, decreasing non-radiative recombination even in polycrystalline films. However, these properties are not just optimum for solar cell but for any optoelectronic device, causing that currently the research with these materials widespread to different optoelectronic fields. Among these fields the one that likely has taken more attention has been in light emitting diodes (LEDs), promoted by the high photoluminescence quantum yield (PLQY), especially for perovskite nanoparticles, narrow electroluminescence (EL) peak, providing purer colors, and versatility to tune the bandgap and consequently the emitting color. In this talk, I discuss different strategies to increase the performance, considering both the external quantum efficiency (EQE) and stability), but also the reproducibility. After an intensive work in perovskite LEDs field, it has been a huge improvement in the performance of these devices, however, the two main drawbacks of this system, the use of hazardous Pb and the long term stability, still to be open questions that have not been fully addressed. Preparation and optimization of Sn-based LEDs will be discussed as well as the possibilities of fabrication with industrially friendly methods as inkjet printing. We report as the use of additives and alternative synthesis of microcrystal precursor play a key role in the increase of LED luminance, EQE and stability of Sn-based perovskite LEDs.
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.
