Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV19)
Publication date: 6th February 2020
Hybrid Organic-Inorganic Perovskites have attracted a remarkable attention by the scientific community due to their great properties in the field of Photovoltaics 1–4. Nonetheless, their lack of stability and their loss of performance in humid air ambient5.6, joined with the lack of good uniformity in the large area reachable with the classic spin coating technology, are slowing down their marker uptake. New techniques were recently developed where researcher tried to mix physical deposition techniques with the classic solvent methods by two different steps for the PbI2 and MAI. But in many cases, an additional final solvent treatment must be performed to have good quality films. In this work we have prepared MAPbI3 by a “fully solvent-free” process on different substrates. MAPbI3 were deposited by two steps proximity thermal evaporation technique where the substrate is located close to the melting pot and is self-heated by the reagents powder. The layers deposited were characterized in terms of crystal structure by XRD analyses, that showed the presence only of the main peak related to the MAPbI3 structure, and in terms of morphology by SEM/TEM analyses that revealed a flat uniform coverage of the substrates on flat substrates while flake grain shape on rough FTO substrates. As proof of concept, solar cell architectures were prepared using Spiro-MEOTAD as Hole Transporting Layer and gold to exploit the new up-scalable and clean deposition method.

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.
