Recently, photoexcited hot carriers (HCs) relaxation dynamics in halide perovskite materials have attracted much attention since the HCs cooling lifetimes was found to be unusually slow with orders of magnitude longer compared to those of the conventional semiconductor. On the other hand, the HCs cooling in perovskite quantum dots (PQDs) is size-dependent and the cooling time was observed to be around two orders of magnitude longer than that of their bulk counterparts [1], which suggests that the PQDs are promising candidates for hot-carrier solar cells (HCSCs). Therefore, a deeply understanding the hot carrier cooling and extraction dynamics in the PQDs has a profound implication for further developing the disruptive HCSCs. In this talk, we will introduce our recent research results on hot carrier cooling and extraction dynamics in PQDs, including both experimental results obtained using transient absorption (TA) spectroscopy and DFT theoretical calculation. We will discuss on how the A-site cations cross-exchange of the PQDs affects the hot carrier relaxation dynamics, and how about the hot carrier extraction from the PQDs to inorganic metal oxide substrates and fullerene [2-4].
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.
