Proceedings of Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP20)
Publication date: 14th October 2019
Organic-inorganic hybrid perovskite solar cells have demonstrated
unprecedented high power conversion efficiencies in the past few years. Now, the
universal instability of the perovskites has become the main barrier for this kind of solar
cells to realize commercialization. This situation can be even worse for those tin-based
perovskites, especially for CsSnI3, because upon exposure to ambient atmosphere the
desired black orthorhombic phase CsSnI3 would promptly lose single crystallinity and
degrade to the inactive yellow phase, followed by irreversible oxidation into metallic
Cs2SnI6. By alloying CsSnI3 with CsPbI3, we herein report the synthesis of alloyed
perovskite quantum dot (QD), CsSn1-xPbxI3, which not only can be phase-stable for
months in purified colloidal solution but also remains intact even directly exposed to
ambient air, far superior to both of its parent CsSnI3 and CsPbI3 QDs. Ultrafast
transient absorption spectroscopy studies reveal that the photoexcited electrons in the
alloyed QDs can be injected into TiO2 nanocrystals at a fast rate of 1.12 × 1011 s-1,
which enables a high photocurrent generation in 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.
