Colloidal semiconductor nanocrystals (NCs) are known to play an essential role in the burgeoning next generation optoelectronic devices such as solar cells, photodiodes, light-emitting diodes (LEDs) and field-effect transistors (FETs). We investigate the charge carrier mobility and their recombination dynamics in 1D and 2D semiconductor NCs. The varying anisotropic carrier confinement, effective mass and defect density result in strong tuneability of the carrier mobility and their recombination lifetime. In this study we measure the intraparticle charge carrier mobility and their recombination dynamics in colloidal semiconductor NCs. The electron−hole pairs are generated by using high energy (3 MeV) pulsed electron irradiation that results into a uniform distribution of charge carriers inside the sample. The irradiation induced charge carrier mobility and recombination dynamics are studied using electrode-less time-resolved microwave conductivity technique. The influence of composition, size and anisotropic confinement is investigated. The presented results can be used to improve the performance of nanocrystal based optoelectronic devices.
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.
