Electronically coupled systems constructed out of recently developed Lead halide based Perovskite nanocrystals and Quantum dots could be prospective smart hybrid materials for next generation photovoltaic and optoelectronic devices due to their mutually synergistic interactions. In our present work, we have studied the nature of electronic coupling and photoinduced charge transfer dynamics occurring in CsPbBr3-CdSe nanoplatelet hybrid system being cross-linked with various short chain aliphatic (Glycine) and aromatic (p-Aminobenzoic acid) molecular linkers. Combining time-resolved photoluminescence spectroscopy and transient absorption measurements in correlation with in-situ photoresponse X-ray photoelectron spectroscopy, we provide comprehensive information on the effect of charge distribution modifications, realignment of band edge potentials and subsequent change in exciton binding energy in our hybrid films. These hybrid systems generated an effective p-n heterojunction due to the charge distribution with a built in electric field as controlled by the molecular linkers across the interface between these two disparate materials. Our results demonstrate the pivotal role taken by organic linkers in such hybrid assemblies, and shed new light on past results on perovskite-QD hybrid systems. As such, it establishes new insight on hybrid heterojunctions with potential applications in the design of hybrid devices.
Israel Science Foundation ISF‐NSFC program
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.
