Proliferation of data-intensive applications has posed challenges for existing wireless connectivity. As a potential alternative to existing WiFi technology, optical wireless communication (OWC) integrates data communication with ambient lighting and can act as next-generation high-speed free-space data communication platform. OWC transmits data by modulating light intensity, with data transmission capacity dependent on the switching speed of the emitter. In addition to making faster emitters, the capacity can be enhanced by sending data simultaneously across multiple independent channels at different wavelengths.
In this talk, I will discuss the requirements of novel emitter materials and how to test their merit for application in OWC. My discussion will connect the fields of materials science and photophysics with the application and performance of novel emitters in communication systems.
Based on these considerations, I will highlight the great potential of perovskite nanocrystals for OWC applications and show our recent results towards establishing a multi-channel communication platform based on different perovskite compositions as luminescence converters. In particular, I will discuss how we employed advanced keying schemes and data processing to achieve data transmission rates on the order of Gbit/s.
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.
