Thin-film Photovoltaic Technology Combines Efficiency and Versatility

Stacking solar cells increases their efficiency. Working with partners in the EU-funded PERCISTAND project, researchers at the Karlsruhe Institute of Technology (KIT) have produced perovskite/CIS tandem solar cells with an efficiency of nearly 25 percent – the highest value achieved thus far with this technology. Moreover, this combination of materials is light and versatile, making it possible to envision the use of these tandem solar cells in vehicles, portable equipment, and devices that can be folded or rolled up. The researchers present their results in the journal ACS Energy Letters (DOI: 10.1021/acsenergylett.2c00707)

Argonaut project launches design effort for super-cold robotics

A new robotics project named Argonaut at the Department of Energy’s Fermi National Accelerator Laboratory will share that same name and spirit of adventure. Argonaut’s mission will be to monitor conditions within ultracold particle detectors by voyaging into a sea of liquid argon kept at minus-193 degrees Celsius — as cold as some of the moons of Saturn and Jupiter.
