Organic-inorganic hybrid perovskite exhibits outstanding properties in light emission and photovoltaic applications, exceeding conversion efficiencies of 25%, and fast photodetection response [1]. Thus, considering the size-dependent optical and electronic properties of these materials, the use of perovskite nanocrystals helps to mitigate bulk related issues such as photoinduced halide segregation and crystal phase instability [2]. However, some challenges still need to be addressed in terms of device fabrication, particle aggregation, annealing and post-treatment related issues, and environmental instability when assembled [3]. Therefore, using a metal-organic host matrix based on a sol-gel approach [4] as a straightforward method for the in-situ and controlled generation of highly stable perovskite nanocrystals (PNCs) stands out as a promising alternative. The optical and electrical properties of these materials are evaluated to enlighten the specific characteristics of this system concerning a perovskite polycrystalline thin film, showing photoluminescence quantum yield exceeding 80%, photocurrent response with an ON/OFF current ratio around two orders of magnitude, and remarkable stability over time when stored under room conditions. We believe that our antisolvent and glovebox-free approach for the preparation of PNCs will pave the road for its application in perovskite photodetectors, among other devices as sensors, and light emitters.
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.
