Some Like it Hot: Simulating Single Particle Excitations

Posted on December 17, 2015 by rberkowitz

Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Now, for the first time, the interplay between the plasmon mode and the single particle excitation within a small metal cluster has been simulated directly. Read more at Berkeley Lab…my last embargo-held press release written while full-time at LBNL, despite the byline! Continue reading →

On the way to Multiband Solar Cells

Posted on November 12, 2015 by rberkowitz

Wladek Walukiewicz of the Materials Sciences Division led the development of the first intermediate band solar cell to demonstrate charge transfer across all three band transitions – valence/intermediate, intermediate/conducting, and conducting/valence. These results open the door to high-efficiency solar cells and multicolor light emitters. Continue reading →
