OPV

Germany-based Credoxys has successfully completed its second funding round, led by deep-tech VC LIFTT and Melchers Group. The company says it will use the funds to commercialize its p-dopant technology in both the Korean and Chinese markets. The company already validated some product candidates with industry partners, and these are ready for customer qualification.

Credoxys is focused on developing novel materials for both the p- and n-sides of OLEDs and organic solar cells (OPVs). The company says its newly developed p-dopants surpass current standards by exhibiting extremely low absorption of visible light and low pixel cross-talk. The materials enable the doping of hole transport materials with deep HOMO levels, making them particularly suitable for phosphorescent blue OLEDs.

Poland is aiming to become a major innovation and high-tech hub, and the country is already enjoying a growing industry, focusing on IT, bio-technology, robotics and nanotechnology.

Poland has a strong material science and development expertise, and in recent years we have been seeing OLED and display-related ventures out of Poland. It seems Poland is poised to become an interesting location to watch for future innovation in the OLED industry.

Ergis Group noDiffusion OLED encapsulation film

One such company is the Poland-based Ergis Group, a leader in plastic processing active in markets such as food packaging, industrial, automotive, medical and more. In 2020, Ergis launched its first product for the optoelectronic applications (such as the display market and photovoltaics) - the Ergis noDiffusion films for flexible OLED panels (both displays and lighting) and OPVs. Ergis is using a unique ALD-based technology that enables it to offer high performance films on low cost PET films.

A new company has recently been launched in Poland, to commercialize a new family of TADF OLED compounds. Noctiluca, which takes its name from a bio-luminescent marine creature, was established a few months ago with aims to be the world's first company to produce a commercial-ready blue TADF emitter.

Noctiluca's story begins with an innovative organic DSSC solar cell platform that was developed at Synthex, an organic chemistry development platform company based in Torun, Poland. A few years ago the researchers turned their attention to light emitting materials (which are quite similar to the light harvesting materials used in solar panels) and intensive research culminated in a promising family of new TADF compounds - which was then spun-off as Noctiluca,

Researchers from Sweden's Chalmers University have developed a new "double doping" process that basically doubles the efficiency of Polymer OLED emitter materials.

The researchers explain that doping in organic semiconductors operates through what is known as a redox reaction, in which the dopant molecule receives an electron from the semiconductor which increases the electrical conductivity of the semiconductor. The efficiency limit of current doped organic semiconductors has been limited by the fact that each dopant molecule was able to to exchange one electron only. In the new research it was shown how it is possible to move two electrons for every dopant molecule which increases the conductivity of the organic material.

The OLED-Info team takes pleasure in recommending our new book - The Perovskite Handbook, which gives a comprehensive introduction to perovskite materials, applications and industry. We believe that any display professional would find that perovskite materials are an area of focus that should not be ignored.

Perovskites offer a myriad of exciting properties and has great potential for the display industry. The promising perovskite industry is currently at a tipping point and on the verge of mass adoption and commercialization and the first display-related perovskites are already reaching the market.

Researchers from Japan's Kyushu University developed a new technology called singlet fission that enables near-infrared OLED materials to surpass the 100% limit for exciton production - or achieve an internal quantum efficiency (IQE) of over 100%. Singlet fission was already used in OPVs, but this is the first time that it was demonstrated with OLEDs.

Achieving over 100% is possible because at 100% IQE all charges form excitons that emit light. The new technique splits the energy from a high-energy excitons into two low level ones. The new OLED emitter materials use molecules in which singlets can transfer half of their energy to neighboring molecules while keeping half of the energy for themselves - each singlet creates two triplets. The emitters emit near-infrared light.

In September 2017, Merck, OLEDWorks, OPVIUS and Kolon launched a new textile-based OLED lighting and OPV installation (called "Do we dream under the same sky") at the first Seoul Biennale of Architecture and Urbanism.

Merck now brought the same installation to Frankfurt during the Light + Building 2018, and the company also gave us more details about this interesting installation.

Merck, OLEDWorks, OPVIUS and Kolon launched a new textile-based "façade" concept that combines OLED lighting panels and OPV (organic PV panels). The new structure was launched as part of the first Seoul Biennale of Architecture and Urbanism.

The façade, in which the structure is made from Bamboo, was designed by architects Nikolaus Hirsch, Michel Müller and artist Rirkrit Tiravanija. The same installation will also be delivered to more exhibitions in Germany and Thailand during 2018.

Leading simulation and measurement tool provider Fluxim recently released a new version of its large-area OLED simulation software LAOSS. The new version adds a simulation capability for temperature estimation and cross-coupling the temperature generated by the device operation itself (in the organic stack and the electrodes) and the changes in device operation due to this increased temperature (leading again to different heat generation and so on).

LAOSS is a software tool that simulates large area semiconductor devices (OLED and PV), taking into account the voltage drop in the electrodes due to important resistive effects when the size of the device increases. LAOSS facilitates electrode layout optimization and material choice, which can save substantial time and resources. Both OLED lighting panel design and study of AMOLED pixel cross-talk is just a click away.
