The recent combination of functional scanning probe microscopy with data science techniques has started to yield interesting new insights into a wide range of materials. Large multimodal datasets comprising many different measurements on the same area can reveal structure-function relationships beyond that of any single technique. As an example, combining photoluminescence mapping with electrical current measurements in conductive atomic force microscopy shows how the perovskite-electrode contact affects functional solar cells by correlating optical properties with electrical function. Such multidimensional approaches are particularly attractive given the recent emergence of techniques like photoinduced force microscopy (PiFM) that can measure vibrational spectroscopy with nanometer spatial resolution, thereby combining chemical and electrical information. In this talk I will discuss our recent work in functional imaging of materials using data-driven scanning probe methods, from sub-microsecond time-resolved electrostatic force microscopy (trEFM) to multimodal analysis using hyperspectral PiFM. These methods allow for investigation into spatially-dependent properties of nanostructured photovoltaics, such as the nature of grain boundaries in perovskite active layers. While I will focus primarily on hybrid organic-inorganic perovskites, I will also discuss how these techniques reveal new insight into mixed ionic-electronic conductors and nanostructured polymers.
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.
