Figure 3

Interfacial donor–acceptor energetics derived from gas-phase DFT calculations for GQDC42 and GQDC42-PhCOOH sensitizers and from UPS for tin oxide. Frontier orbital distributions of HOMO and LUMO for both sensitizers are also presented. The Fermi level for the tin oxide sample is within the oxide CB, indicating strong n-type character.
