Metal halide perovskites (MHPs), particularly CsPbBr₃, have emerged as a transformative material for optoelectronic applications, offering unparalleled properties such as high carrier mobility, exceptional optoelectronic performance, large photoluminescence quantum yield, and superior stability under humidity and thermal stress. Its solution processability allows for easy fabrication using inkjet printing, an environmentally sustainable alternative to conventional manufacturing techniques [1].
In inkjet printing of perovskites, the characteristics of the functional ink and printing conditions are crucial in determining the final device performance, with annealing temperature playing a critical role in influencing the crystal structure and, consequently, the optoelectronic properties of the printed films. This study comprehensively investigates the impact of annealing temperature in vacuum oven from 45-200 °C on the properties of inkjet-printed CsPbBr₃ nanocrystal films printed on glass substrate [2]. The CsPbBr₃ nanocrystal inks were prepared in the ratio of 3:1 in dodecane and hexane solvent with each nanocrystal measuring 7-13 nm and the printing was performed using Dimatix inkjet printer.
The results reveal a significant dependence of photoluminescence (PL) intensity on the annealing temperature, with the optimal PL emission observed for devices annealed at 180°C. The change in the PL properties are related to the impact of annealing temperature on grain size, crystallinity, and film uniformity, which directly affect optoelectronic properties and stability corroborated by various characterizing techniques such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, and ultraviolet-visible (UV-Vis) absorption spectroscopy providing conclusive evidence of the temperature-induced changes in crystal structure, phase purity, and optoelectronic performance. These findings underline the critical role of precise thermal processing in achieving high-performance inkjet-printed perovskite films, positioning CsPbBr₃ as a viable material to be printed on ITO coated glass substrate for LED applications [3].

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.
