Investigating the Dynamics of Charge Transfer in Solar Cells

Tandem organic solar cells have drawn much attention in the field of solar energy. They consist of two monolithically connected cells enabling a broader absorption spectrum and efficient use of photon energy. In a Nature Communications article, entitled “High performance tandem organic solar cells via a strongly infrared-absorbing narrow bandgap acceptor,” researchers use the ultrafast … Continue reading

Observing the Surface-Enhanced Signal of Water in an Aqueous Dispersion

Researchers from the Polish Academy of Sciences, Lodz University of Technology, and the University of Warsaw use a PHAROS laser from Light Conversion to observe the surface-enhanced (SE) signal of water in an aqueous dispersion of silver nanoparticles. The observation techniques used were spontaneous Surface-Enhanced Raman Spectroscopy (SERS) and Surface-Enhanced Femtosecond Stimulated Raman Spectroscopy (SE-FSRS) processes. This work opens up exciting … Continue reading

Studying Ultrafast Relaxation Processes in Ag Nanocubes

Noble metal nanoparticles patterned in ordered arrays interact and generate plasmonic surface lattice resonances. Up to now, the assumption was that such nanoparticles are static. But researchers from the Kaunas University of Technology in Lithuania have demonstrated that this is not the case at ultrafast time scales. They used Transient Absorption Spectroscopy (TAS) to study … Continue reading
