Avantama
Switzerland-based Avantama AG (previously called NanoGrade) is specialized in the development and supply of printable and coatable materials for the manufacturing of optical or electronic thin films. Avantama's materials are based on liquid formulations and inks containing semiconducting metal oxides or luminescent perovskite quantum dots.
In November 2024, as part of a move to bring Avantama’s pQD market-ready technology into the hands of a company with market and customer access, Avantama decided to sell its pQD IP portfolio and related know-how and manufacturing assets.
Avantama's QDs show several differences when compared to other commercial QDs (CdSe and InP): the chemical composition is based on metal halide perovskites such as e.g. CsPbBr3, the QD color is mainly controlled by the chemical composition and not by the QD size, no additional inorganic shell is needed for high quantum efficiency and stability and more.
Avantama states that its metal halide perovskite QDs yield the highest possible quantum efficiencies of > 95% which will result in best peak brightness of LCD displays.

Avantama to sell its perovskie QD IP portfolio
Switzerland-based Avantama, a leader in high-tech materials for electronics, has brought its perovskite QD (pQD) technology to “market-ready” level. Avantama's CEO, Dr. Samuel Halim states that reliability (as QD film) was confirmed by leading display supply chain partners, the pQD production has been established in-house and the pQD film production has been established at a leading Asian film maker.
Now, as part of a move to bring Avantama’s pQD market-ready technology into the hands of a company with market and customer access, Ocean Tomo Transactions (a part of J.S. Held) will be representing Avantama in the sale of its pQD IP portfolio and related know-how and manufacturing assets.
Avantama and Scrona make strides in perovskite quantum dots processing
Swiss additive manufacturing startup Scrona and Avantama, developer and manufacturer of high-tech materials for electronics, have jointly announced that they have successfully processed high-performance perovskite quantum dot (QD) ink using Scrona's electrohydrodynamic (EHD) inkjet printing.
This collaboration combines the benefits of the inkjet process with high-patterning resolution to drive a new generation of efficient and cost effective MicroLED displays, while also increasing color purity and brightness, and improving overall pixel production tact time.
Researchers improve inverted perovskite solar cells with antimony-doped tin oxides
Researchers at the National University of Singapore (NUS), Chinese Academy of Sciences (CAS) and Avantama have developed a new interface using antimony doped tin oxides (ATOx), that creates a chemically stable interface between the cell layers that's more uniform, conducts electricity better, and is more transparent. This enabled reduced energy loss and improved cell efficiency - 25.7% (certified steady-state efficiency of 24.8%) for an area of 0.05 cm2, retained under maximum power point tracking over 500 h and 24.6% (certified steady-state efficiency of 24.0%) for an area of 1 cm2.
The team reported p-type antimony-doped tin oxides (ATOx) combined with a self-assembled monolayer molecule as an interlayer between the perovskite and hole-transporting layers (HTL) in inverted solar cells. The scientists said that ATOx increases the chemical stability of the interface; they showed that the redox reaction that commonly took place at the NiOx/perovskite interface is negligible at the ATOx/perovskite interface.
The MicroLED Industry Association to host a Perovskite microLED technology webinar
On March 27 the MicroLED Industry Association will host a private webinar on perovskite materials for the microLED industry. Perovskite materials hold great promise for the solar industry and in recent years we are seeing promising signs for the adoption of perovskites the display industry.
The upcoming Seminar will feature four world-leading speakers, and will also be open to a Q&A session. We will learn more about the state-of-the-art perovskite research and development, with a focus of course on applications in the microLED industry - for both perovskite QDs and PeLEDs.
DSCC: perovskite-based QD films for LCD applications could enter the market in 2022
Display market research firm DSCC says that perovskite-based QD films for LCD display applications could enter the market in 2022. DSCC says that perovskite materials could increase efficiency and color gamut compared to current solutions.
Last year we reported that Zhijing Nanoech has concluded a successful pilot with TCL, which has produced 500 75-inch QD-enhanced LCD TVs with Zhijing's PQDF films. The company hopes to achieve a design win with TCL for mass production.
