Major leap for stable high-efficiency perovskite solar cells

Solar cells manufactured from materials known as "perovskites" are catching up with the efficiency of traditional silicon-based solar cells. At the same time, they have advantages of low cost and short energy payback time. ...

Soaking up the sun with artificial intelligence

The sun continuously transmits trillions of watts of energy to the Earth. It will be doing so for billions more years. Yet, we have only just begun tapping into that abundant, renewable source of energy at affordable cost.

Nontoxic material found to be ultra-strong solar energy harvester

Solar cells are vital for the green energy transition. They can be used not only on rooftops and solar farms but also for powering autonomous vehicles, such as planes and satellites. However, photovoltaic solar cells are ...

Marrying models with experiments to build more efficient solar cells

In a single day, enough sunlight strikes Earth to power the world for an entire year—that is, if we can find a way to capture that energy cheaply and efficiently. While the cost of solar energy has decreased dramatically, ...

Sponge-like solar cells could be basis for better pacemakers

Holes help make sponges and English muffins useful (and, in the case of the latter, delicious). Without holes, they wouldn't be flexible enough to bend into small crevices, or to sop up the perfect amount of jam and butter.
