The largest project in history, under the ocean: 5,000km and two continents linked by this

Envision a settlement where the sunlight that beams across Australia buoy on its vast outback powers millions of homes and industries across Southeast Asia. This is how the Australia-Asia PowerLink (AAPowerLink) is being realized: the longest sub-sea cable in the world, linking northern Australia to Singapore, presently is one of the all-time break-through renewable energy developments. By virtue of this mammoth solar farm with its advanced energy transmission technology, this ambitious vision will shape the future energy systems around the world while addressing some critical climate issues.

Taking enormous advantage from its plentiful sunlight, northern Australia houses the world’s biggest Solar Precinct in its Northern Territory gathering between 17–20 GW peak electricity, a size surpassing that of Australia’s largest coal-fired power station.

The project incorporates advanced storage of 36–42 GWh, supplying 800 MW to Darwin and 1.75 GW to Singapore. In addition to reducing emissions and electricity prices for the Darwin region, it creates a renewable energy export marketplace for the region and demonstrates the use of the solar-rich area to meet 15 percent of Singapore’s electricity demand.

Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings

When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule’s chemical structure due to an increase in the molecule’s internal energy. These processes typically take just tens of picoseconds (one millionth of a millionth of a second). Advanced capabilities at X-ray free electron laser (XFEL) facilities now enable scientists to create images of these ultrafast structural changes.

In work appearing in The Journal of Physical Chemistry A, researchers found structural evidence of a strained bicyclic molecule (a molecule consisting of two joined rings) that emerges from the chemical reaction that occurs when a cyclopentadiene molecule absorbs UV light. Cyclopentadiene is a good sample chemical for studying a range of reactions, and these findings have broad implications for chemistry.

Highly strained molecules have a variety of interesting applications in solar energy and pharmaceuticals. However, strain doesn’t typically occur naturally—energy must be added to a molecular system to create the strain. Identifying processes that produce molecules with strained rings is a challenge of broad interest in physical chemistry.

US-China crack code for toxic-free solar panels with 20% efficiency

A new design principle has been identified that could eliminate the use of toxic chemicals in solar cell manufacturing.

The standard manufacturing process of organic cells involves toxic solvents. This environmental concern has hindered the widespread adoption of organic solar cells.

Researchers at Linköping University (LiU) have revealed a new design principle for eco-friendly, high-efficiency organic solar cells.

Artificial photosynthesis learned from nature: New solar hydrogen production technology developed

Researchers have successfully developed a supramolecular fluorophore nanocomposite fabrication technology using nanomaterials and constructed a sustainable solar organic biohydrogen production system.

The research team used the good nanosurface adsorption properties of tannic acid-based metal-polyphenol polymers to control the and optical properties of fluorescent dyes while also identifying the photoexcitation and electron transfer mechanisms. Based on these findings, he implemented a solar-based biohydrogen production system using bacteria with hydrogenase enzymes.

The findings are published in the journal Angewandte Chemie International Edition. The joint research was led by Professor Hyojung Cha at the Department of Hydrogen and Renewable Energy, Kyungpook National University and Professor Chiyoung Park at the Department of Energy Science and Engineering, Daegu Gyeongbuk Institute of Science & Technology.

Dynamics of self-hybridized exciton–polaritons in 2D halide perovskites

Basically I believe that this could be the answer for solar panels having super high output as exciton polariton energy is very powerful.

Self-hybridized exciton–polaritons are shown to enable sub-bandgap absorption and emission in 2D perovskites. The energy absorbed by the perovskites are also found to transfer to few-layer graphene in a heterostructure.

Japan eyes next-gen solar power equivalent to 20 nuclear reactors

The Japanese government is planning to generate some 20 gigawatts of electricity, equivalent to the output of 20 nuclear reactors, through thin and bendable perovskite solar cells in fiscal 2040.

TOKYO (Kyodo) — The Japanese government is planning to generate some 20 gigawatts of electricity, equivalent to the output of 20 nuclear reactors, through thin and bendable perovskite solar cells in fiscal 2040.

Quantum Breakthrough Allows Researchers To Create “Previously Unimaginable Nanocrystals”

The type of semiconductive nanocrystals known as quantum dots is not only expanding the forefront of pure science but also playing a crucial role in practical applications, including lasers, quantum QLED televisions and displays, solar cells, medical devices, and other electronics.

A new technique for growing these microscopic crystals, recently published in Science, has not only found a new, more efficient way to build a useful type of quantum dot, but also opened up a whole group of novel chemical materials for future researchers’ exploration.

“I am excited to see how researchers across the globe can harness this technique to prepare previously unimaginable nanocrystals,” said first author Justin Ondry, a former postdoctoral researcher in UChicago’s Talapin Lab.
