A research team has used x-ray photoelectron spectroscopy to observe charge motions in light-excited molecules of thiouracil, a modified nucleobase.

Using time-resolved X-ray photoemission spectroscopy, scientists are for the first time analysing at the femtosecond scale the processes in a model system for organic solar cells.

Titanium dioxide (TiO2) is one of the most promising materials for photovoltaics and photocatalysis nowadays. This material appears in different crystalline forms, but the most attractive one for applications is “anatase”. EPFL scientists have now shed light onto the problem by a combination of steady-state and ultrafast spectroscopic techniques, as well as theoretical calculations.
