At its CES 2016 press event today Samsung unveiled its 2016 SUHD TV lineup that features Quantum dot display. The 2016 SUHD TVs boast the world’s only cadmium-free 10-bit Quantum dot display which promises true-to-life picture quality, exceptional contrast and brightness as well as the most lifelike colors ever offered by a Samsung TV. Quantum dots: PV has anchored its place as one of the most promising renewable energy technologies owing to its operational feasibility, durability and ease of maintenance.
Market penetration of competitive PV technologies is limited mainly by cost, which in turn depends on device efficiency, material availability and the energy requirement of production process. Nanoscale semiconductors can exhibit shifts in absorption spectra with varying particle sizes. In the early 90s, dye-sensitized solar cells (DSC) made a breakthrough by having devices work with 7% efficiency.
Despite these advantages, some of the best laboratory efficiencies of quantum dot-sensitized solar cells (QDSC) are around 4-5%, approximately half that of a DSC. Recent reviews for QD-sensitized solar cells have focused on narrowing down the performance-limiting factors and possible solutions.
Based on the current state of research, the Achilles heel for QDSCs has not been identified yet. Mit leistungsstarken neuen Panels und Bildverbesserungsverfahren bestechen die SUHD TVs vor allem durch ein uberragendes Seherlebnis, das bislang mit der LCD-Technologie nicht moglich schien. Das Spitzenmodell der neuen Samsung SUHD TVs uberzeugt Tester durch beeindruckende Farbbrillanz, hervorragende Ausstattung und edles Design. Durch edles Metall, hochwertige Verarbeitung und besondere Stilelemente werden SUHD TVs zu Design-Objekten. Samsung SUHD TV vereint die Vorzuge bisheriger Paneltechnologien und erzielt uberragende Testergebnisse in Sachen Bildqualitat.

Samsunga€™s latest SUHD smart TVs are wickedly thin and nearly devoid of bezels, but their most interesting feature is inside the chassis: An integrated smart hub capable of controlling more than 200 of Samsunga€™s Smart Things connected-home devices.
The company says these hubs can automatically detect the presence of connected-home devices, virtually eliminating the tedious process of enrolling each sensor, light, smart door lock, security camera, and other components. The new line also has enough processor horsepower to play videogames without the need to plug in a gaming console. Unlike Panasonic, which announced at IFA that it was switching from LCD to OLED technology for its flagship smart TV, Samsung is sticking with LCD and (cadmium-free) quantum dots. Samsung also announced last night that it was taking preorders for its first Ultra HD Blu-ray player, the UBD-K8500 that was announced last fall at IFA.

This afternoon during its annual Spring Launch event, South Korean tech giant Samsung announced pricing and availability for its 2016 SUHD TV lineup, including a newly announced flagship TV series, the KS9800. The TVs range from an entry-level 49-inch for $1,499 through the gargantuan 88-inch KS9800, which will retail for $20,000. The KS9800 series is particularly surprising, since usually giant TVs with eye-popping price tags are announced at CES back in January. For more information and a harder look at the tech specs, check out our breakdown of Samsung's 2016 TV lineup. Samsung also announced the availability of two new wireless soundbars: the HW-K950 and HW-K850, which feature Dolby Atmos support.

All functionality, features, specifications, GUI and other product information provided in this document including, but not limited to, the benefits, design, pricing, components, performance, availability, and capabilities of the product are subject to change without notice or obligation. The company says that its new lineup provides unparalleled picture quality and has the world’s first bezel-less curved design. All of Samsung’s SUHD TVs this year feature high dynamic range (HDR), light reflection is further reduced by the new Ultra Black technology. Within this field, quantum dot (QD) semiconductors have, of late, drawn a large number of PV researchers. PV device researchers focus on incorporating novel concepts and device modification to optimize the solar cells which have already reached commercial production. Having the right sizes and combination of QDs leads to broader coverage of the incident spectrum. Within two years, the efficiencies reached the 10% mark required for a PV device to be considered viable.
One common argument presented is that there has been two decades’ worth of research on DSC compared to the emerging QD-sensitized cells. Unlike first and second generation solar cells, dye or QD-based solar cells work on different principles.

Some of the initial hype about quantum dots replacing dyes was overshadowed by limited device performance. Mit 60 Watt Ausgangsleistung – inklusive Woofer – bei dem 65 Zoll (163 cm) Modell und sogar 70 Watt bei den Bildschirmdiagonalen von 78 (198 cm) bzw. Durch die neue Anordnung der Apps an der unteren Bildschirmleiste und einem leistungsstarken Achtkern-Prozessor des JS9590 ist die Bedienung noch intuitiver und schneller als zuvor. Daher setzt Samsung auf hochwertige Metallgehause und elegante Stilelemente wie die lamellierte Ruckwand des JS9090 oder den abgeschragten Rahmen des JS9590. At a press event last night, Samsung showed games such as Assassina€™s Creed III, Batman: Arkham Legends, and Ultra Street Fighter IV running on the TVs, and the company says more than 500 other titles are available, in partnership with Sonya€™s PlayStation Now game-streaming service. The company intends to ship the new player, which can deliver four times the resolution of Blu-ray discs, to the U.S. He built his own smart home in 2007, which he uses as a real-world test lab when reviewing new products. Their TVs have already been rather sleek, not to mention rather innovative too if you consider the fact that Samsung has been introducing more curved TVs to its lineup, and the recently announced KS9500 is no exception.This SUHD curved TV was announced at CES 2016 and is actually the successor to last year’s JS9500 model, so if you liked what you saw last year, then this year’s KS9500 should be no exception. We should have eyes on with the new flagship soon, but in the meantime here's how the rest of the lineup is shaking out. The K950 stands out as the first soundbar to be bundled with two Atmos-compatible satellite speakers.

Smart Hub offers quick, direct access to all the essential functions and content you need from live TV, Over The Top (OTT), Games and more. The contents within the screen are simulated images and are for demonstration purposes only. It has already confirmed that the entire 2016 lineup has integrated Internet of Things (IoT) hub technology and is protected by its GAIA security solution for smart TVs. Samsung KS9500 SUHD TV is the first bezel-less curved TV and it provides an exceptional immersive viewing experience as the viewer’s attention is focused entirely on the content. Plan B is to come up with an alternative PV technology starting with noble material selection and working all the way up to full-scale production. This is fairly challenging in conventional solar cells since it would require alloys as absorbers with varying compositions to begin with. Till now the DSCs work with an accepted efficiency of 11% and have made their way into PV markets. That, of course means detailed material and device characterization has been done for DSC which will help shed light on where QDSCs are falling short. Light absorbers – commonly referred to as sensitizers – are at the heart of the device which helps to convert photons to electrons. In situ, methods like successive ionic layered absorption and reaction (SILAR), chemical bath deposition (CBD) and electrodeposition let the QDs grow directly onto the porous substrates.
Concentration of the deposited cadmium selenide is higher than that of cadmium sulphide for the same deposition cycles. There have also been investigations of silicon QDs as down converters and in tandem-cell application. Mai 2015 – Wer einen neuen Fernseher fur ein atemberaubendes Heimkino-Erlebnis sucht, trifft mit den jetzt im Handel erhaltlichen Samsung SUHD TVs buchstablich eine ausgezeichnete Wahl. SUHD TV vereint die Vorzuge bisheriger Paneltechnologien fur eine deutlich sichtbare und spurbare Verbesserung der Bildqualitat.
Mit Innovationen und dem Streben, immer wieder Neues zu entdecken, verandern wir die Welt von Fernsehern, Smartphones, Wearables, Tablets, Kameras, Druckern, Hausgeraten, Netzwerk-Systemen bis hin zu Medizintechnik, Halbleitern und LED-Losungen. In fact, the entire smart-home user interface, running on Samsunga€™s Tizen operating system, can appear on the TV, where you can interact with it using the TVa€™s remote if you find that more convenient than using your smartphone or tablet. Hardcore gamers would likely cringe at the frame rates and visual quality, but casual gamers should enjoy it.
Samsung announced last night that its 2016 lineup is among the first to earn Ultra HD Premium certification from the UHD Alliance, thanks in part to their ability to display 10-bit color and to produce 1000 nits of brightness. The TV will be made with Samsung’s 360 design, meaning that the TV was created to look good from the front and the back, as you can see in the photos above and below.

Another smart use of QDs is down converters which make use of the size-dependent photoluminescence characteristic. These sensitizers need hole-transporting materials (HTM) like liquid or solid state electrolytes to regenerate the sensitizers as well as to collect the electrons at the counter electrode. This shows that use of dual sensitizers to some extent bypasses the surface coverage issue of QDSCs.
While there have not yet been any tandem cells based on QDs, the highest success for down conversion technique was a 10% efficiency improvement for polycrystalline silicon cells. Dies unterstreichen aktuelle Produkttests von Fachmedien, in denen die Spitzenmodelle JS9590 und JS9090 von Samsung hervorragende Bewertungen erzielen. Der Status als Referenz unterstreicht dies eindrucksvoll“, sagt Kai Hillebrandt, Vice President CE Samsung Electronics GmbH. Unsere Initiativen, unter anderem in den Bereichen Digital Health und Smart Home, machen uns zudem zu einem Schrittmacher fur das Internet der Dinge. Samsung said it has partnered with 20th Century Fox to bring 30 moviesa€”including The Martian and Peanutsa€”to Ultra Blu-ray.

Besides PV, they have applications in areas of photocatalysis, image sensors, light emitting diodes, high efficiency transistors and optical communication.
In this process, QDs absorb photons of a shorter wavelength (blue region) and emit them back at a longer wavelength (red region) where the device has high quantum efficiency. In situ methods are the preferred techniques for better electron transport and higher QD absorption.
Proper surface treatments and the right protective layers would reduce electron recombination and stabilize the QDs. Coming back to QDSCs, accounting for the fabrication limitations together with correct and optimized device configuration is needed as a first step to reach a credible performance.
Das Modell UE65JS9590 wird gleich funfmal von Area DVD, Audiovision, Heimkino, Hifi Test und video zur aktuellen Referenz gekurt1, was bedeutet, dass sich vergleichbare TV-Gerate fortan an diesem Modell messen lassen mussen.

Their name comes from their appearance as little dots which are roughly around 1 to 10 nanometers in size. Researchers came up with alternative liquid electrolytes amongst which polysulphide liquid electrolyte proved to be a fairly good HTM for QDSCs, “fairly good” here referring to picoseconds hole injections from QDs to electrolytes. For the cadmium sulphide deposition via SILAR method, only around 20% of the available titanium dioxide porous film surface area is covered. As a secondary step, the introduction of back reflectors and a light scattering layer, further optimization with down conversion – incorporating plasmonic metals or even the generation of multiple EHPs, can push the efficiency limit even higher. QDs have a couple of significant features which attracted PV researchers in the first place. Again, most dyes do not have response beyond the visible region, leaving the entire infrared part of the spectrum (49% of total solar radiation) unutilized. A new problem arose due to polysulphidenot having good catalytic activity with platinum, the doping material for DSC counter electrodes.
The QD particles get deposited in the early stages of fabrication and later cycles only add to those particle growths, ceasing increased surface coverage.
One of the most talked-about concepts is the generation of multiple electron-hole pairs (EHP) from one photon. Things can pick up for QDSCs only if the optimized efficiency is reasonably high, which would make it cost effective to go for the additional performance enhancing techniques. Commercially established PV devices based on silicon and thin film depend on micrometer-thick layers of materials for sufficient light absorption. Concentration of QDs not only limits the photocurrents but also, having a large surface area uncovered leaves a higher chance of electron recombination with the electrolyte. Although this has been proven experimentally for QDs, it seems a little far-fetched for QDSCs. Reflecting on the current volume of research, the question as to whether or not QD-based devices will reach commercial production level efficiency is likely to be answered soon. QD nanoparticles, having high absorption, hold the promise of significantly reducing the absorber material requirement.
Until now, copper (I) sulphide on brass counter electrode and polysulphide electrolyte have been accepted staples for QDSC. This effectively decreases the internal shunt resistance of QDSCs resulting in low fill factors (40%-60%) compared to that of DSCs (~70%). This process requires at least twice the amount of energy for particles to be generating more than one EHP per photon. Commonly investigated QD materials like cadmium selenide, lead sulphide, cadmium sulphide and indium phosphide typically have a couple of orders’ higher absorption than silicon and thin film materials. This makes DSC and QDSC devices similar in architecture but different in material selection. Recently electron recombination via surface defects in the QDs itself has been identified as a viable pathway for electron recombination. The energy limit of our solar spectra to around 3.5eV narrows down the QD materials available to be implemented experimentally. This incompatibility has dealt a blow to the possibility of dyes and QDs being used together as co-absorbers in one system.
This is exclusive to QDSCs and raises the question of the limitations of deposition methods. Recent research into plasmonic metals could bring in a fresh perspective for improving QDSC performance. However, the catch with QDs is their size-dependent spectral response and photoluminescence.
Finally, most QD semiconductors used for QDSCs are heavy-metal-based compounds making them unlikely candidates for green energy.
Metals like copper, gold and silver have response to visible light which triggers a highly concentrated electric field around these particles.
First and second generation solar cells depend solely on electric field for charge separation. Incorporation of plasmonic metals with QDs is relatively new and has the potential to build better devices.
