Organic-inorganic hybrid perovskite formamidinium cesium lead triiodide NH2CHNH2CsPbI3 (FACsPbI3) has better thermal stablity than methylammonium lead triiodide CH3NH3PbI3 (MAPbI3), so it be research recently. And in order to improve the efficiency and ambient stability, the FA0.9Cs0.1PbI3 perovskite precursor is added the other larger cation hexylammonium iodide(HAI) and after annealing to form 2D-3D mixed peroskite, that will improve the stability in ambient atmosphere, because the 2D structure has better moisture barrier abilities than the 3D structure. And then the 2D-3D mixed peroskite of HAI2(FA0.9Cs0.1)n-1PbnI3 perovskite films are post-treated with hexylammonium iodide through spin-coating again. However, it can form a protective layer on the surface of perovskite to barrier the surrounding, and the moleculers of cations will flow into the grain boundaries to reduce defects between grain boundaries, and make the electrons and holes transfer easier to improve the efficiency of the perovskite. After our experiments, it was found that the post-treated cells actually increased efficiency by about 2%, and have better moisture stability.
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.
