The module's angled, sloping walls bounce reflected light directly toward opposing surfaces, offering a secondary chance for photon absorption. Testing revealed a maximum power output increase of up to 142.3% compared to conventional flat units under identical conditions. Furthermore, the underlying flexible, printed polymer mechanical metamaterial allows the system to bend without breaking. This breakthrough could eventually enable seamless power generation across aerospace equipment, electric vehicles, and curved architecture.

Bees have inspired engineers to rethink solar panel design. The honeycomb structure behind their hives has provided a blueprint for tackling a persistent problem: sunlight reflecting away from panels instead of generating electricity. Conventional flat panels receive sunlight more directly around midday, but the sun's changing angle affects how much light they capture.
Engineers have developed a concave, three-dimensional design that redirects reflected light towards another surface, giving it a second chance to be absorbed. According to a report by The Pulse, the honeycomb-inspired structure increased maximum power output by 142.3% compared with a flat panel under the same conditions, offering a way to reduce wasted sunlight without tracking motors.
Why angled sunlight creates a problem for solar panels
Traditional solar panels have a flat surface. As the sun moves across the sky, its rays strike that surface at different angles. When sunlight arrives at an oblique angle, reflection from the protective glass becomes a problem. Light that bounces away cannot contribute to the panel’s electricity output.
The honeycomb-inspired design changes the path of that reflected light. Rather than relying…
Alice Huang, described as a "Chinese spy," left the company Megaspeed in 2025 amid an ongoing row involving Nvidia. Following the development, Megaspeed stated that it conducted "legitimate and lawful business."
The regional Nvidia cloud computing partner is navigating severe geopolitical scrutiny after U.S. intelligence linked a former top shareholder to Chinese intelligence collection efforts. These allegations culminated in the resignation of Nvidia's chief executive and sparked inquiries into whether advanced chip infrastructure was improperly accessed. The company maintains full compliance with export controls while working to dispel allegations of unauthorized technology diversion.
A routine fiber optic upgrade conducted by contractor L3Harris caused radar gaps across 17 air traffic centers, prompting a four-hour nationwide ground stop. The disruption triggered over 14,000 flight cancellations across two days, marking the only full domestic halt since September 11, 2001. Federal officials confirmed the telecommunications failure stemmed from overloaded routers rather than a cyberattack.
