X-rays reveal details of plastic solar cell production

Plastic solar cells are light, easy to install, and readily produced using a printer. Nevertheless, the processes that take place on the molecular scale during the production of organic solar cells are not yet entirely clear. Researchers have now managed to observe these processes in real time. Their findings could help to improve the efficiency of organic solar cells.

Perpetual youth for batteries?

A key issue with lithium ion batteries is aging. It significantly reduces their potential storage capacity. To date, very little is known about the causes of the aging effects. Scientists have now come a step closer to identifying the causes in their latest experiments.
