Researchers at The Hong Kong Polytechnic University (PolyU) have developed a perovskite-organic tandem solar cell that remains highly efficient under partial shading. The cells retained more than 90% of their initial efficiency after exposure to a severe -40 V reverse-bias voltage, which can permanently damage conventional thin-film solar cells. Why Shading Damages Solar Cells Partial shading from clouds, trees, buildings, or birds can force shaded cells into reverse bias, re

Anthropic will restore global access to its Fable 5 and Mythos 5 models after the U.S. Department of Commerce lifted export restrictions that had blocked them earlier this month. On Tuesday, the company announced it would begin gradually restoring access to its most advanced AI models. In a post on X, Anthropic said: "We have been notified that the Department of Commerce has lifted the export controls on Claude Fable 5 and Mythos 5. We will begin restoring access tomorrow." T

This advanced manufacturing technology enables the production of ultra-precise structures with gaps as small as 6 nanometers and could allow the integration of millions of qubits on a single chip. Silicon quantum dots are considered one of the most promising approaches for large-scale quantum computing because they are compatible with existing semiconductor manufacturing infrastructure. Today, the main challenge is not creating qubits but scaling them up to industrial levels.
