    Perovskite/CIGS Tandem Solar Cell Sets 22.4% Efficiency Record

    Materials scientists at the University of California, Los Angeles (UCLA) have set a new power conversion efficiency record with a conventional CIGS solar cell by depositing an inexpensive perovskite layer atop the original device, boosting its...

    Transparent Optics-Less Camera Uses Window as Lens

    Engineers at The University of Utah (US) have created an optics-less camera that can use a regular pane of glass or any see-through window as the lens. “We showed that by placing an image sensor — with no optics — at the edge of a...

    Inverse Charge-Funneling Enables Hot-Carrier Extraction

    A technique discovered by researchers at the University of Exeter in the UK allows for the movement of excited charges through a non-uniform energy-gap landscape. This effect could make solar cells three times more efficient by...

    Autonomous Soaring with Onboard Solar Power

    Combining autonomous soaring and onboard solar power, new technology developed at the U.S. Naval Research Laboratory (NRL) allows unmanned aerial vehicles (UAVs) to fly for more than 12 hours.  The solar-soaring technology uses both thermal...
