Hole-transporting layers (HTLs) are an essential part of an organic photovoltaic (OPV) device stack. Currently, printable HTLs do not typically offer compatibility with next-generation active layer materials such as PM6 and Y-series NFAs. The research team at Brilliant Matters has been working to address these and other issues. They have recently launched BM-HTL-1 BM-HTL-1 is a fully printable, high-work function hole-transporting layer (HTL) designed for use in organic optoelectronic devices such as solar cells or photodetectors. It is aimed at delivering good film properties, wettability, and processability while retaining favorable electronic properties for optoelectronic applications. Designed for good compatibility with modern donor polymers having energetically deep HOMO levels, BM-HTL-1 can eliminate the need for evaporated hole transport layers in organic solar cells. It is a printable organic alternative to MoOx and is more energetically suitable (deeper work function) than PEDOT: PSS for OPV applications. Technical features include :

•Ethanol-based formulation with low water content for printed electronics.

•Energetically deep work function (5.5-5.6 eV), enables the use of deep HOMO level polymers and reduces the need for evaporated HTL layers such as MoOx during device prototyping.

•Printable in thick layers (~200 nm) while maintaining function as an HTL (critical for large-scale OPV Printing)
•Conductivity (average): 0.4 S/Cm@200nm film

QDs can be used in multiple ways in modern TVs. The NanoPalomaki has been doing excellent teardowns. As shown in slide one, in the majority of cases a QD film is used to convert blue LED light to red and green. As shown in slide 2, sometimes there is both QD and phosphor included in the display In the newest high-end implementation (QD-OLED, slide 3) uses patterned QDs atop a blue OLED backlight. Peter from NanoPalomaki will present the latest tear-downs at TechBlick's upcoming event on microLEDs and Quantum dots taking place on 30NOV-1Dec 2022. He will show detailed analysis of our teardowns during this talk, highlighting TVs that have been torn down and analyzed to see where the color is coming from in our QLED displays.

AI, wearable electronics, skin patches, and stretchable electronics? Precision medicine, the future landscape of healthcare, can provide personalized diagnosis and treatments to each individual by taking into account the underlying differences in people’s genes, ages, health histories, and living environments. This futuristic healthcare requires the development of two major capabilities: (1) the effective and continuous acquisition of multi-modal health data during long-term daily activities outside of clinics, for which wearable electronics emerge as the ideal solution; and (2) the high-throughput and intelligent analysis of such complicated and large-quantity dataset for extracting the underlying personalized health patterns, which is becoming one of the main application directions of artificial intelligence (AI).
Prof Sihong Wang from University of Chicago will present a solution on 2-Dec-2022 at the free-to-attend TechBlick event www.TechBlick.com/wearables He will first introduce his research in imparting skin-like stretchability onto wearable sensors that can continuous collect health data on the human body. Then he will introduce hisr research in imparting intrinsic stretchability onto neuromorphic devices that can provide state-of-the-art computing performance. He will also show the practical applicability of this device for implementing machine-learning computing and algorithms for health data analysis, when the computing hardware is under human-body-induced deform...

What are the advantages, challenges, and requirements of microLEDs in different application sectors? This is an important question with strategic consequences, particularly as the application space is diverse, including almost disparate sectors such as automotive, wearables, smartphones, TVs, etc. In the table in slide 1 below, Reza from VuReal offers his perspective, outlining the key advantages of microLEDs, the key challenges, and also key technological requirements from the perspective of microLED display and manufacturing. In general, microLED can offer an excellent value proposition in all sectors, provided technology challenges such as cost of manufacturing, bonding, yield and throughput of transfer, size of microLED and PPI, etc can be addressed. In slide 2, Reza et al will outline - based on their perspective, the key technology challenges facing many of the existing solutions: Yield Throughput Cost Performance Reza will present VuReal's technology at TechBlick's microLED and Quantum Dot event on 30Nov-1Dec 2022. The technology is termed MicroSolid Printing, and it is a printing process for integrating micrometer size devices into surface to difference microLEDs. The details will be discussed at the conference. Review the agenda and sign up here www.TechBlick.com/microLEDs...

Even though µ-LED manufacturing has moved forward over recent years, it is still in early development stage, resulting high costs and poor yields. Thus, finding pathways to reduce manufacturing costs and improve overall yield is of major interest to the industry. An alternative path would be to replace the solder paste in solder paste printing by plating process. To solve this issue Atotech Group has developed a new auto-catalytic tin process that can overcome the thickness limitation of existing immersion tin process. This process works fully autocatalytic and by this has no limitation on the underlying metal type or tin layer thickness. By this plating on substrates like e.g. Cu, Pd, Au or Ni have been realized without the chemical attack on the underlying layer. In order to reduce the chemistry consumption and chemical waste a regeneration unit is available to recover the reducing agent and run the plating solution in cycle. This allows a cost competitive plating solution with fine line capabilities which provide benefits over conventional printing methods. To learn more about this exciting development, join us on 30NOV-1Dec for a world-class event on microLEDs featuring the likes of Sharp, Samsung, Allos Semiconductor, Omdia, ASMPT, Yole, Nanosys, Epistar, Coherent, MKS, and many more.

Perovskite quantum dots (PeQDs) offer ultranarrow FWHM and emission even when manufactured at low temperature with relatively high defect densities. The red PeQDs remain elusive due to instability challeges. However, the green one is already stable enough. Avantama will be presenting exciting results at the TechBlick conference on microLEDs and Quantum Dots on 30-Nov-2022 and 2-Dec-2022, showcasing how PeQDs can deliver value as conversion films in miniLED LCDs and as color converters in microLEDs. See full agenda and register here www.TechBlick.com/microLEDs MiniLEDs In the first slide below, you can see a color conversion film composed of green PeQDs (by Avantama) and red KSF phosphors. The red KSF phosphors offer five ultra narrow red peaks. They are now an established solution in many backlight systems in which they are used as the red phosphor directly on the LED chip. The unique combination (gree PeQD and red KSF phosphor) thus marries the best performance, combining narrow emission of green PeQD with narrow emission and proven stability of KSF phosphors. The emission spectrum of the yellom color conversion sheet is shown in slide one. This sheet can be applied to LCD displays with min-LED backlights. The results are shown in slide 2. Here, one can see that the PeQD+KSF film allows 40% higher brighness when compared with a low-Cd QD-only color conversion film. It also offers a slighly wider color gamut. This proves that this is a good solution performance-wise But the q...
