Light harvesting devices need to combine strong absorption in the visible spectral range with efficient ultrafast charge separation. Artemis can directly measure change in electron populations, to obtain information on the charge separation and recombination times.

The recombination pathways of charge carriers are also important to photocatalysis because they determine the lifetime of chemically active sites and hence the catalytic efficiency.
