While hybrid perovskite solar cells exhibit remarkable power conversion efficiencies, the challenges associated with their limited stability, scalability, and molecular-level engineering remain unresolved.[1-2] Although some of these limitations could be overcome by employing electronically compatible and hermetically sealing hydrophobic materials, enhanced stabilities are mostly achieved at the expense of the efficiency of the corresponding devices.[3-5] Our alternative strategy provides stabilization without compromising the efficiency by utilizing judiciously designed multifunctional molecular modulators (MMMs) through fine-tuning of noncovalent interactions complemented by structural adaptability.[2,4-5] These systems are designed to interact with the perovskite surface in a manner uniquely assessed by solid-state NMR spectroscopy.[2,4] As a result, we realize novel layered two-dimensional perovskite materials[6] and obtain durable and scalable perovskite solar cells with superior properties and efficiencies exceeding 20% for formamidinium cesium mixed lead iodide perovskite compositions, accompanied by elevated tolerance to environmental factors.[2] This approach has been investigated by using a combination of techniques, including scanning electron microscopy, cathodoluminescence mapping, X-ray diffraction, and photoluminescence spectroscopy in conjunction with solid-state NMR spectroscopy to unravel the underlying mode of action and exemplify the advantages of multifunctional molecular modulation in perovskite solar cell research.
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.
