Energy transport in emerging materials is an important emergent property to characterize at the nanoscale, especially since they often contain nanoscale heterogeneities. I will therefore share recent advances in detecting, tracking, and discerning the spatiotemporal evolution of charge carriers, excitons, heat and ions as they interconvert and explore emerging materials’ structure and heterogeneity on multiple scales. I will share our development of sub-picosecond and single-digit nanometer sensitivity stroboscopic optical scattering microscopy (stroboSCAT) through a series of examples of increasing complexity. Beginning with charge carrier transport in solution-processed semiconductors and extending the approach to thermal transport in a wide range of materials opens the possibility to study these different forms of energy simultaneously. Building on these capabilities to also incorporate multiple photogenerated electronic species in transition metal oxide photoelectrodes provides an unique opportunity to elucidate the role of transport in promoting artificial photosynthesis. I will also show a similar approach to follow mass transport associated with electrochemical CO2 reduction and the most direct measurements to-date of exciton transport in natural photosynthesis.
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.
