Organic-inorganic heterojunction is a widely used architecture in technologically relevant materials such as light-emitting diodes, field-effect transistors and photovoltaic cells. For that reason, controlling the geometrical structure such as the molecular ordering and the molecular orientation at the interface is important for efficient charge transfer. Inspired by the previous study on the control of metal phthalocyanine (MPc) orientation on Si substrate [1], we performed first- principle studies on how the orientation of metal, namely Zn and Cu, phthalocyanine orientation on indium tin oxide (ITO) differs at the introduction of CuI substrate, as experimentally shown by Kim et al. [21]. We showed that the binding occurs between the metal atom in MPc and Cu at the surface of CuI. Furthermore, selective d-d orbital coupling between MPc and Cu-terminated CuI substrate causes CuPc, whose dx2-y2 orbital is half-filled, and ZnPc, whose dx2-y2 orbital is fully-filled, to adopt the “lying-down” and “standing-up” orientation, respectively.
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.
