Why perovskite solar cells tend to segregate under the influence of light
Solar cells made of perovskite are cheap, easy to produce, and almost as efficient as silicon, the material traditionally used in solar cells.
However, perovskite...
New molecular glue makes perovskite solar cells super tough
A “molecular glue” dramatically increases the stability and reliability of perovskite solar cells over time, researchers report in a new study.
The treatment, which keeps...
