Galaxies in a cosmic house of mirrors

Image: This NASA/ESA/CSA James Webb Space Telescope Picture of the Month features galaxies in great detail that have been warped and multiplied like they’ve stepped into a house of mirrors. The brilliant golden galaxies splashed across this image belong to a galaxy cluster called MACS J0454.1-0300.

Polymer-tuned perovskite creates high-efficiency underwater solar cells

A novel crystallization approach boosts submerged solar cells to unprecedented stability, enabling effective conversion of filtered submarine light into sustainable underwater power The post Polymer-tuned perovskite creates high-efficiency underwater solar cells appeared first on Physics World .

  • Researchers at Yunnan University developed a perovskite solar cell for underwater use.
  • Tuning the perovskite's optical bandgap to 1.96 eV maximizes efficiency in deep water.
  • Underwater testing achieved 34.71% efficiency and 5.49-year lifespan.
