Researchers examine room-temperature superfluorescence in hybrid perovskites

Researchers from North Carolina State University and CNRS have reported room-temperature superfluorescence in hybrid perovskite thin films. 

Their work shows that in this material platform, there exists an extremely strong immunity to electronic dephasing due to thermal processes. To explain this observation, the team proposed that the formation of large polarons in hybrid perovskites provides a quantum analogue of vibration isolation to electronic excitation and protects it against dephasing even at room temperature.

HZB sets new tandem solar cell world record, using MBRAUN systems

This is a sponsored post by MBRAUN

For years, the Helmholtz-Zentrum in Berlin has been researching the development of highly efficient perovskite tandem solar cells with great success. The HySprint Innovation Lab was founded specifically for this purpose, which cooperates internationally with other research groups as well as with industrial partners.

Many process steps are necessary to produce these highly efficient perovskite cells, which can all be realized together in the HySprint laboratory. A good research environment and high-quality equipment allow researchers to work optimally on their projects. The results at HZB are impressive. In recent years, the researchers have made significant progress in the field of perovskite tandem solar cells and achieved independently certified world record of tandem solar cells.

Researchers develop perovskite solar panels with a thermally stable device stack

A research team led by Imec, that also included teams from Hasselt University and Kuwait University, has fabricated a perovskite solar module based on a scalable, stable device stack that can be processed with industry-compatible techniques, such as sputtering, evaporation, and slot-die coating.

The panel is based on 17%-efficient perovskite solar cells built with a p-i-n configuration, an electron transport layer made of nickel(II) oxide (NiOx), a perovskite layer deposited via slot-die coating, an electron transport layer made of buckminsterfullerene (C60) and lithium fluoride (LiF), a bathocuproine (BCP) buffer layer, and a copper (Cu) electrode.

Researchers create a material for processing and storing quantum computing information

Researchers from North Carolina State University, University of North Carolina at Chapel Hill, Massachusetts Institute of Technology (MIT),  National Renewable Energy Laboratory, Duke University, Wayne State University and The Hong Kong University of Science and Technology have created a mixed magnon state in an organic hybrid perovskite material by utilizing the Dzyaloshinskii-Moriya-Interaction (DMI). 

The resulting material has potential for processing and storing quantum computing information. The work also expands the number of potential materials that can be used to create hybrid magnonic systems.

Greatcell Australia and First Graphene explore graphene enhancements to perovskite solar cells

It was recently reported that Greatcell Australia is working with graphene company First Graphene on graphene enhancements to perovskite solar cell technology.

Greatcell Australia has reportedly established a pilot plant in New South Wales and is in the advanced stages of testing its range of perovskite solar cells (PSCs) with manufacturers around the world. “Greatcell is aiming to modularize their production lines for product flexibility, due in part to the easier assembly and reduced number of steps to produce PSCs compared to silicon solar cells.”

Researchers design a slot die-coated perovskite solar panel with improved efficiency retention

Scientists from Nanyang Technological University, along with their collaborators, have fabricated a slot die-coated perovskite solar panel that reportedly offers remarkable efficiency retention.

The researchers used a hydrophobic, all-organic salt known as fluorinated anilinium benzylphosphonate (FABP) to modify the top surface of large area slot-die coated methylammonium (MA)-free halide perovskite layers. The salt acts as a molecular lock that is able to bind to both anion and cation vacancies, which significantly increases the materials' intrinsic stability.

Researchers examine a perovskite-based electrolyte developed for SOFCs

Solid oxide fuel cells, or SOFCs, are a type of electrochemical device that generates electricity using hydrogen as fuel, with the only 'waste' product being water. 

To potentially accelerate the development of more efficient SOFCs, a research team from Kyushu University, Yamagata University and Kyushu Synchrotron Light Research Center has uncovered the chemical innerworkings of a perovskite-based electrolyte developed for SOFCs. The team combined synchrotron radiation analysis, large-scale simulations, machine learning, and thermogravimetric analysis, to uncover the active site of where hydrogen atoms are introduced within the perovskite lattice in its process to produce energy.
