Flexible perosvkite solar cell sets efficiency record

C&EN: Aperovskite solar cell has set a new efficiency record for flexible thin-film photovoltaics, with an independently-verified power conversion efficiency of 24.4%, (Nat. Energy 2022, DOI: 10.1038/s41560-022-01045-2). The device is a tandem cell, and beats the previous flexible thin-film champ…

Holes help shed light on novel medical devices

Materials Today: Holes help to make sponges and English muffins useful (and in the case of the latter, delicious). Without holes, sponges wouldn’t be flexible enough to bend into small crevices, and muffins wouldn’t be able to sop up the perfect…

Nuclear waste energy could power the US for a century, scientist says

E&T Magazine: There is enough energy in the nuclear waste in the United States to power the entire country for 100 years with clean energy, according to Jess C. Gehin from the Idaho National Laboratory. Scientists have long known the potential…

Engineers Are Working on a Solar Microgrid To Outlast Lunar Nights

IEEE Spectrum: The next time humans land on the moon on the moon, they intend to stay awhile. For the Artemis program program, NASA and its collaborators want to build a sustained presence on the moon, which includes setting up a…
