Photogeneration yield spectrum

WebOct 6, 2024 · We start by surveying the evidence for non-unity photogeneration yield (PGY). Next, characterization methods which allow quantifying wavelength dependent PGY are proposed. Finally, we discuss the implications of these findings and suggest future research directions to characterize them. Export citation and abstract BibTeX RIS Next article in issue WebSep 1, 2024 · If photogeneration proceeds through low-energy relaxed CT states, we expect similar field dependence of CT dissociation yield for all the photon energies, as the hot CT states will ther- mally relax to the lowest lying CT state before separation.
