World’s largest solar mural turns 34,500 sqft wall into power generator
The SunRise Building, a residential complex in Alberta, Canada, has established a Guinness World Record for the largest solar panel mural.
The installation combines art with building-integrated photovoltaics (BIPV), contributing to the building’s energy supply. This project measures 34,500 square feet and provides 267 kW of solar capacity, powering the building’s common areas.
New method replaces nickel and cobalt in battery for cleaner, cheaper lithium-ion batteries
A team of McGill University researchers, working with colleagues in the United States and South Korea, has developed a new way to make high-performance lithium-ion battery materials that could help phase out expensive and/or difficult-to-source metals like nickel and cobalt.
The team’s breakthrough lies in creating a better method of producing “disordered rock-salt” (DRX) cathode particles, an alternative battery material. Until now, manufacturers struggled to control the size and quality of DRX particles, which made them unstable and hard to use in manufacturing settings. The researchers addressed that problem by developing a method to produce uniformly sized, highly crystalline particles with no grinding or post-processing required.
“Our method enables mass production of DRX cathodes with consistent quality, which is essential for their adoption in electric vehicles and renewable energy storage,” said Jinhyuk Lee, the paper’s corresponding author and an Assistant Professor in the Department of Mining and Materials Engineering.
Nanosheet material stores heat below 100°C using dual water adsorption modes
Efficiently capturing and storing excess heat, particularly below 200°C, is paramount to achieving a carbon-neutral society. Every year, factories and homes produce excess heat, much of which gets wasted. Likewise, as the world gets more reliant on renewable energy sources, the need to capture and store heat grows.
A collaboration between Tohoku University and the Japan Atomic Energy Agency has made significant strides in this regard, developing nanosheets of layered manganese dioxide (MnO2) that can store heat even below 100°C.
Details of the study were published in the journal Communications Chemistry.
EVs Getting Cleaner More Quickly Than Expected in Europe: Study
As the push for sustainable transportation intensifies globally, a new study from the International Council on Clean Transportation (ICCT) reveals that battery-electric vehicles (BEVs) in Europe are becoming significantly cleaner at a pace faster than previously anticipated. This development comes as the continent’s electricity mix transitions toward more renewable sources, providing a profound climate advantage over traditional internal combustion engine (ICE) vehicles.
Key Findings of the Study
Released on Wednesday, the ICCT study highlights that BEVs sold in Europe today produce 73 percent fewer life-cycle greenhouse gas emissions compared to ICE vehicles. This figure marks a noteworthy 24-percent improvement from the organization’s prior estimates in 2021, emphasizing the rapid progress of BEVs as Europe enhances its renewable energy initiatives.
Defects in single-crystal indium gallium zinc oxide could fix persistent display instability
Many displays found in smartphones and televisions rely on thin-film transistors (TFTs) made from indium gallium zinc oxide (IGZO) to control pixels. IGZO offers high transparency due to its large bandgap (the gap existing between the valence and conduction bands), high conductivity, and can operate even in an amorphous (non-crystalline) form, making it ideal for displays, flexible electronics, and solar cells.
However, IGZO-based devices face long-term stability issues, such as negative bias illumination stress, where prolonged exposure to light and electrical stress shifts the voltage required to activate pixels. These instabilities are believed to stem from structural imperfections, which create additional electronic states—known as subgap states—that trap charge carriers and disrupt current flow.
Until recently, most studies on subgap states focused on amorphous IGZO, as sufficiently large single-crystal IGZO (sc-IGZO) samples were not available for analysis. However, the disordered nature of amorphous IGZO has made it difficult to pinpoint the exact causes of electronic instability.
