Perovskite materials whose size and composition can be adjusted to “tune” the wavelengths of light they absorb, making them a favorable and potentially lower-cost, high-efficiency emerging tandem technology.

Inverted perovskite solar cell breaks 25% efficiency record

Researchers improve cell efficiency using a combination of molecules to address different issues

Northwestern University researchers have raised the standards again for perovskite solar cells with a new development that helped the emerging technology hit new records for efficiency.

By listening to activities recorded by the Global Seismographic Network station, located to the north-northeast of Reykjavik, Iceland, people can hear how the seismic activity has changed around the Fagradalsfjall area. Photo by Toby Elliott for Unsplash

Listen to Iceland’s recent seismic activity

Seismologist: ‘The activity is formidable, exciting and scary’

As seismic activity intensifies ahead of an impending eruption of a fissure near Iceland’s Fagradalsfjall volcano, the island’s Reykjanes Peninsula is experiencing hundreds of earthquakes per day.

Now, listeners can follow along …
