Perovskite-Info: the perovskite experts

Perovskite-Info is a news hub and knowledge center born out of keen interest in the wide range of perovskite materials.

Perovskites are a class of materials that share a similar structure, which display a myriad of exciting properties like superconductivity, magnetoresistance and more. These easily synthesized materials are considered the future of solar cells, as their distinctive structure makes them perfect for enabling low-cost, efficient photovoltaics. They are also predicted to play a role in next-gen electric vehicle batteries, sensors, lasers and much more.

LayTec’s new InspiRe in-situ tool used for monitoring perovskite formation

Germany-based in-situ metrology system maker LayTec has announced that its new InspiRe system applies high-speed in-situ reflectance measurements for monitoring perovskite thin-film formations during spin-coating and subsequent annealing.

LayTec’s new InspiRe in-situ tool for control of perovskite formation image

In collaboration with professor Norbert Nickel’s group at HZB, LayTec designed the InspiRe in-situ metrology system, which was applied to monitor both spin-coating and annealing. Gathering data at a time resolution on the millisecond scale allows resolving of the kinetics and phase formations during film formation.

Researchers develop ultrafast, broadband perovskite photodetectors for large-dynamic-range imaging

Researchers at the Chinese Academy of Sciences (CAS) and other collaborators have reported a solution-processed broadband photodetector based on organic-inorganic hybrid perovskite and organic bulk heterojunction, achieving broadband response spectra up to 1000 nm with a high EQE in the NIR region, an ultrafast response speed of 5.6 ns and a wide linear dynamic range of 191 dB.

The team stated that thanks to the high-dynamic-range imaging capacity, high-quality visible-NIR actual imaging is obtained, enabling the accelerated translation of solution-processed photodetector applications from the laboratory to the imaging market.

Hexagonal perovskites hold great potential for ceramic fuel cell technology

Researchers from the University of Aberdeen have reported that a new family of chemical compounds known as ‘hexagonal perovskites’ could be extremely beneficial for ceramic fuel cell technology and reducing global carbon emissions.

Ceramic fuel cells are highly efficient devices that convert chemical energy into electrical energy and produce very low emissions if powered by hydrogen, providing a clean alternative to fossil fuels. Another advantage of ceramic fuel cells is that they can also use hydrocarbon fuels such as methane, meaning they can act as a ‘bridging’ technology which is an important asset in terms of the move away from hydrocarbons towards cleaner energy sources.

New perovskite-based catalsyt could enable cost-effective and efficient Metal-Air batteries

Researchers from Korea's Ulsan National Institute of Science and Technology (UNIST) developed a new perovskite-based catalyst that could enhance the charge-discharge performance of Metal-Air Batteries (MABs). MABs are very interesting as they are lightweight, affordable and has a large storage capacity, but current metal-based catalysts are too expensive for wide commercial adoption.

The new catalyst is made from a very thin layer of metal oxide film that is deposited on a surface of perovskite catalysts. This new so-called "composite catalyst" combines the two types of catalysts each with its own excellent performance for charging (metal) and discharging (the perovskite catalyst).

KAUST and University of Toronto team develops perovksite-silicon tandem cell with 25.7% efficiency

Scientists from the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia and University of Toronto, have developed a perovskite-silicon tandem solar cell which they claim showed excellent operational stability under accelerated tests.

The device was made by combining solution-processed, micrometer-thick perovskite top cells with fully textured silicon heterojunction bottom cells.

EPFL team uses perovskites to show how magneto-optical drives could be cheaper and faster than HDDs

Physicists at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland have used perovskite materials to alter a magnetic bit’s polarity with light, potentially opening the door to denser and faster disk drives using magneto-optical technology.

EPFL introduces perovskite-based light-operated hard drives image

Researchers László Forró, Bálint Náfrádi, Péter Szirmai and Endre Horváth suggest magneto-optical drives using this method could be physically smaller, faster and cheaper than today’s disk drives. They also say it is an alternative to heat-assisted magnetic recording (HAMR).

ANU reaches 27.7% efficiency with silicon/perovskite tandem solar cell

Researchers at The Australian National University (ANU) have announced an impressive achievement - a silicon/perovskite tandem solar cell with a conversion efficiency of 27.7%.

Professor Kylie Catchpole says this would only need to improve slightly - to around 30% - before the technology could be rolled out around the world. "In comparison, typical solar panels being installed on rooftops at the moment have an efficiency around 20%" Professor Catchpole said.
