A multi-institution team of researchers led by Indiana University chemist Sara Skrabalak has been awarded $1.8 million from the NSF to establish a research center focused on transforming nanocrystal discovery and design.
Halide perovskite can make solar cells a thousand times thinner than today’s silicon solar cells. A new approach allows scientists to watch changes in the material’s structure and functional properties while the material solidifies into a thin film from solution. This gives new insight into how the material’s structure and functionality are related, aiding in future solar cell design.
In modern optoelectronic devices, performance depends in part on the movement of excitons. Researchers have now created a new perovskite nanocrystal system and taken direct visualizations of the movement of an exciton from crystal to crystal over a record 200 nanometers, much longer than the previous record. This paves the way for new commercial application.
A team of researchers co-led by Berkeley Lab and Columbia University has developed a new material called avalanching nanoparticles that, when used as a microscopic probe, offers a simpler approach to taking high-resolution, real-time snapshots of a cell’s inner workings at the nanoscale.
