Recently, much interest for the development of high-mobility n-type organic semiconductors has arisen because of their essential roles for realizing high-performance optoelectronic devices, such as ambipolar organic field-effect transistors (FETs), organic and perovskite solar cells (OSCs/PSCs), and organic light-emitting diodes (OLEDs). Despite their wide range applicability, much less n-type organic semiconductors have been developed compared to remarkable progress of p-type ones due to the several issues including required high electron affinity, crystallinity, electron-trapping, and air-stability.
We have recently investigated on molecular designing and optimization of charge transport properties of naphthalene diimide (NDI)-based n-type small molecules. From simple substitution of functional alkyl, aromatic, or fused aromatic units at N and N’ positions of NDI derivatives, we could effectively control their molecular stacking modes and charge transport properties. This presentation will report on the elaboration of vertical and lateral electron mobility of NDI derivatives based on the controlled molecular stacking, and suggest an approach to improve high vertical electron mobility for the application of NDI derivatives as an electron transport layer in perovskite solar cells.
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.
