Great Perovskite article. That could solve a Perovskite use problem for many applications. I don't know if QMC needs it for their QDX Perovskite, but could be.
Here's what they announced about QMC Perovskite in September 2018:
Quantum Materials Corp Announces Capability to Mass Produce High Performance, Low Cost Perovskite Quantum Dots - Paving the way for Next Generation Solar and Display Applications Incorporating PQD Materials
Low Cost, Next-Generation Perovskite Quantum Dots with High Performance & Reliability Now Possible
San Marcos, TX, Sept. 18, 2018 (GLOBE NEWSWIRE) -- Leading American cadmium-free quantum dot manufacturer Quantum Materials Corp (OTC:QTMM) today announced it has developed a continuous flow manufacturing process to produce stable, low cost, high purity perovskite quantum dots (PQDs).
Perovskite quantum dots are leading a breakthrough in materials technology, but the commercialization of these materials has been hampered due to inabilities to produce large volumes of these materials at low cost points while still achieving long term reliability. Quantum Materials Corp has developed a high volume production process that produces extremely high purity PQDs with significantly improved stability.
PQDs have many unique properties that make them an ideal material for utilization in applications such as next generation solar cells and displays. For instance, in solar cells perovskites have demonstrated conversion efficiencies of 22.7% which is higher than today’s best dye-sensitized or thin-film technologies (CiGS, CdTe) and can also extend efficiency (up to 1.3x) of silicon PVs when coated as an absorption enhancement layer. High purity PQDs hold the promise to achieve high conversion efficiencies while also solving many of the reliability and stability challenges.
As a phosphor replacement in flat panel displays, PQDs have the potential to provide industry best color gamut picture qualities due to their extremely narrow emission wavelength profile. For comparison, todays industry leading low cadmium or cadmium free QLED displays can only deliver roughly an 80% Rec 2020 coverage while PQDs have the ability to deliver roughly a 98% Rec 2020 coverage (with properties that include: PLQY>95%, FWHM <25 nm and adjustable peak position).
"With our continuous flow process technology QMC can produce high purity PQD’s at a fraction of the cost of the high purity silicon used in silicon solar cells and with solution processing these materials are compatible with monomers for easy implementation utilizing roll-to-roll coating technologies" stated Toshi Ando, Director of Business Development for Quantum Materials Corp.
QMC is the first to adapt a mature mass-production technology to perovskite quantum dot production. With nearly a decade of continuous flow quantum dot development experience, QMC is uniquely positioned to respond to the emerging market for high purity uniform quantum dots and nanoparticles. “It was not surprising to us that through our patented flow process we have been able to enhance the reliability and stability of perovskite quantum dots. In addition to high volume and low production cost the QMC flow process consistently accelerates discovery and produces extraordinary results. As we are approaching the final stage of bringing to market our first commercial level red-green QD infused film component, we see tremendous potential in advancing the performance level of our QD based film components even further with the incorporation of PQD's to bring the color gamut up to nearly 100% of the new color standard Rec 2020 coverage, which will set a new standard in flat panel display color rendering" stated Quantum Materials CEO, Stephen Squires.
