A breakthrough for solar durability: UNSW researchers discovered that thicker aluminum oxide layers protect TOPCon solar cells from UV damage by blocking hydrogen migration.
The culprit? High-energy UV photons break chemical bonds, releasing hydrogen that degrades performance. But 7nm AlOx layers act as an effective barrier.

Thicker alumunium oxide layers can reduce ultraviolet-induced degradation in TOPCon solar cells
UNSW researchers developed an experimentally validated model linking UV-induced degradation in TOPCon solar cells to hydrogen transport, charge trapping, and permanent structural changes in the passivation stack. They show that thicker aluminum oxide layers significantly improve UV resilience by limiting hydrogen migration, offering clear guidance for more robust TOPCon designs.

ERA 100 (FF) English Alt Text: A black-and-white photo shows a metallic electric kettle partially hidden among a dense tangle of leafless branches and twigs. The kettle sits outdoors, possibly on a wooden surface, and reflects light off its smooth surface. In the background, a concrete or stone structure adds to the impression of abandonment or neglect. The contrast between the modern appliance and the natural overgrowth suggests themes of decay, forgotten objects, or nature reclaiming space. …
ERA 100 (FF) English Alt Text: A black-and-white photograph shows a stack of cut logs piled outdoors. The logs are arranged horizontally, with rough bark and visible rings. Above the pile, leafy branches from a tree extend into the frame from the upper left, casting soft shadows. On the right, part of a building with a balcony is visible, featuring a hanging plant. A wire runs diagonally across the image from the top right corner. The scene feels rustic and natural, suggesting a rural or semi-…
ERA 100 (FF) English Alt Text: A grayscale image features the upper portions of two buildings with traditional-style rooftops. Both buildings have air conditioning units mounted on their exterior walls. A cluster of electrical wires connects to the building on the right, and several power lines run diagonally across the sky. A utility pole is visible on the right edge. The architectural style and infrastructure suggest an older urban setting, possibly in East Asia, with a mix of tradition and …
ERA 100 (FF) English Alt Text: A monochrome image captures a metal gate with wire mesh, set within a fence made of similar material. The gate is closed and slightly weathered. Behind it, dense vegetation and trees fill the background. In the distance, a faint mountain peak is visible through a hazy sky. Several utility wires stretch horizontally across the top of the image. A piece of cloth or paper is caught on the gate. The scene evokes a sense of enclosure and quiet isolation in a rural lan…

Rent-Only Copyright Culture Makes Us All Worse Off
In the Netflix/Spotify/Amazon era, many of us access copyrighted works purely in digital form – and that means we rarely have the chance to buy them. Instead, we are stuck renting them, subject to all kinds of terms and conditions. And because the content is digital, reselling it, lending it, even preserving it for your own use inevitably requires copying. Unfortunately, when it comes to copying digital media, US copyright law has pretty much lost the plot.

Not the first thought that comes to mind, but this is an #environmental problem, not just about skiing or a local economy:
"Ropes once used to mark out the piste hang in tatters and bits of plastic are falling off a pylon. The old sheds at each end of the ski lifts often still contain transformers, asbestos, motor oils and greases. Over time, these substances seep into the soil and…

Ilford HP5 Plus 400 (FF) English Alt Text: A black and white photo of a modern urban scene featuring a large abstract metallic sculpture and surveillance equipment. The sculpture consists of stacked concentric metal rings curving upward in a spiral, resembling a futuristic tower. It stands among trees, suggesting a public park or plaza. To the left, a utility pole supports two surveillance cameras and a box with signage. The box displays Chinese characters and the word “Video,” along with a …
Ilford HP5 Plus 400 (FF) English Alt Text: An outdoor urban scene with a striking abstract sculpture as the focal point. The sculpture has a mirrored surface and a geometric design: a pyramid-like top transitions into a fluid, distorted base. It sits on a white pedestal in a landscaped plaza with ornamental grasses and trees. Parked cars line the background street, and a signboard is visible nearby. The sculpture’s reflective surface captures surrounding light and movement, creating a dynami…
Ilford HP5 Plus 400 (FF) English Alt Text: A stone sculpture of a person seated on the ground with knees drawn up, arms resting on the knees, and head bowed. The figure appears to be emerging from or partially enveloped by a rough-textured stone, blending human form with natural material. Set on a grassy area beside a sidewalk, the sculpture is surrounded by trees and a distant building, suggesting a park or campus. The posture conveys introspection, solitude, or emotional resilience, inviti…
