The emergence of perovskites as sought-after semiconductors owes to their unique electronic band structure, inherent defect tolerance, increased conversion efficiencies, synthetic flexibility, cost-effectiveness, near-unity PL quantum yield, narrow emission bandwidth, high solar cell efficiencies, etc. All these properties are due to the dynamic nature of the ground and excited states. These hybrid systems have strong electron-phonon interactions which manifest strongly in their optical and photovoltaic behaviours. A critical factor for understanding the light mater interaction is the direct observation of the ultrafast coupling between lattice phonon modes and the charge carriers. Using IVS, we were able to directly visualize light induced carrier- phonon interactions by observing the strong oscillatory features dressing the charge transfer and recombination kinetics of charge carriers. We observe not only the phonon modes coupling to the charge carriers in individual 2D layer with strong electron-phonon interaction but also the triggering of the coherent phonon modes in 3D layers upon charge transfer process completion. Finally, we present that upon suitable structural engineering of the interface, via epitaxial growth, we can efficiently transfer not only charge carrier but also trigger coherent phonon modes which can help improve charge recombination and protect carriers from trap states.
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.
