The capacity to capture and convert solar energy into efficient, environmentally friendly, and renewable power sources has wide-ranging implications globally, spanning scientific and technological domains. Halide perovskites (HPs) exhibit remarkable performance in optoelectronics and photovoltaic devices, making them promising materials for various applications. Nonetheless, their widespread adoption faces obstacles due to their intrinsic instability and toxicity, resulting in detrimental phase changes and decomposition when exposed to environmental factors. A practical approach to overcome these challenges entails developing a protective shell surrounding the core perovskite. This shell acts as a physical barrier, providing stability to the perovskite and augmenting the optical characteristics of the core material. Herein, we developed a new synthetic strategy for stabilizing HPs and boosting their optoelectronic properties by sheeting the NCs with MoS2. We investigate the synthesis mechanism by analyzing each step using a gamut of analytical methods. Namely, we study the mechanism of MoS2 shell formation around the CsPbBr3 NCs by examining the impact of the reaction temperature and the concentration of the precursors. Moreover, the analysis of the optical properties of the core-shell nanostructures indicates a charge transfer from the conduction band (CB) of the CsPbBr3 NCs to the CB of MoS2. This study's insights can guide the design and optimization of stable photonic and optoelectronic HPs-based devices. Moreover, it can address the urgent need to develop sustainable and efficient energy technologies and pave the way toward a more sustainable future.

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.
