ZURICH, Jan. 23, 2024 /PRNewswire/ -- Scrona AG, the additive manufacturing startup and world record holder of the smallest ever printed color picture, and Avantama, a leader in high-tech materials for electronics, today announced that they have successfully processed high-performance 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. 

Key Points: 
  • "We continue to find new applications of EHD that will meet the demands of the industry by offering an additive, completely waste-free process with higher resolution capabilities than lithography patterning," said Dr. Patrick Galliker, co-founder and CEO of Scrona.
  • "Conventional inkjet printing is not a viable option for emerging MicroLED displays because they use much smaller pixels than QD-OLED displays," said Dr. Norman Lüchinger, co-founder and CTO at Avantama.
  • Scrona print head technology processes QD inks using EHD inkjet printing, whereby droplets are ejected from a nozzle by electrostatic forces.
  • Perovskite QDs have the highest weight-based absorption compared to others QDs, and this directly translates to very high OD/thickness values.

BUSAN, South Korea, Jan. 4, 2024 /PRNewswire/ -- Perovskite materials are still attracting a lot of interest in solar cell applications. Now, the nanostructures of perovskite materials are being considered as a new laser medium. Over the years, light amplification in perovskite quantum dots has been reported, but most of the works present inadequate quantitative analysis. To assess the light amplification ability, "gain coefficient" is necessary, whereby the essential characteristic of a laser medium is revealed. An efficient laser medium is one that has a large gain.

Key Points: 
  • Over the years, light amplification in perovskite quantum dots has been reported, but most of the works present inadequate quantitative analysis.
  • Now, in a recent study, a team of researchers, led by Professor Kwangseuk Kyhm from Pusan National University in Korea, has managed to enhance signal amplification in perovskite nanosheets of CsPbBr3 with a unique waveguide pattern.
  • Prof. Kyhm explains: "Perovskite nanosheets can be a new laser medium, and this work has demonstrated that light amplification can be achieved based on tiny perovskite nanosheets that are synthesized chemically."
  • Title of original paper: Gain enhancement of perovskite nanosheets by a patterned waveguide: excitation and temperature dependence of gain saturation

Thursday, June 22, 2023

SINGAPORE,  June 22, 2023 /PRNewswire/ -- Perovskite solar cells designed by a team of scientists from the National University of Singapore (NUS) have attained a world record efficiency of 24.35% with an active area of 1 cm2. This achievement paves the way for cheaper, more efficient and durable solar cells.

Key Points: 
  • Prior to the record-breaking feat by the NUS team, the best 1-cm2 perovskite solar cell recorded a power conversion efficiency of 23.7%.
  • "To address this challenge, we undertook a dedicated effort to develop innovative and scalable technologies aimed at improving the efficiency of 1-cm2 perovskite solar cells.
  • He added, "Building on more than 14 years of perovskite solar cell development, this work represents the first instance of an inverted-structure perovskite solar cell exceeding the normal structured perovskite solar cells with an active area of 1 cm2, and this is mainly attributed to the innovative charge transporting material incorporated in our perovskite solar cells.
  • Since inverted-structure perovskite solar cells always offer excellent stability and scalability, achieving a higher efficiency than for normal-structured perovskite cells represents a significant milestone in commercialising this cutting-edge technology."

Key Points: 
  • We have developed the world’s first rollable and fully printable solar cell made from
    perovskite, a material that is much less expensive to produce than silicon.
  • The silicon solar cells that are so recognisable to us have a significant limitation.
  • In research labs, using highly controlled production methods in environments where oxygen and water are completely removed, perovskite solar cells can now match the electricity generation of silicon solar cells.
  • But cheap perovskite solar cells that do away with silicon have yet to be manufactured on a commercial scale.

How our solar cell works

    • In the past, this had been achieved by heating gold in a vacuum until it evaporated, and catching the vapour on the perovskite solar cell to form electrodes.
    • The result is large volumes of flexible, rollable solar cells that come out of the printing press ready to generate power.

More work needed

    • The 10% power conversion efficiency achieved by these rollable printed cells is useful, and higher than the first commercial silicon panels.
    • There is an engineering challenge to overcome in order that high-volume, commercially produced perovskite solar panels can match the energy generation of silicon.
    • But the possibility of producing hundreds of thousands of square metres of flexible perovskite solar cells is now a step closer.
