Scientists found using a chromium seed layer allowed them to grow ultrathin gold film that serves as a transparent electrode with good conductivity for perovskite solar cells. Image: Penn State

Developing new ultrathin metal electrodes has allowed researchers to create semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices.

The automotive electric vehicle revolution is paving the way for urban air mobility, but people must not be naive in thinking that electric vehicle batteries will suffice for electric flight. The fast-charging requirements, 30x increase in energy throughput, and 3x power requirements demand a new generation of battery. Image: Eric Rountree, EC Power

A team of Penn State researchers are exploring the requirements for electric vertical takeoff and landing vehicles and designing and testing potential battery power sources.
