The Function of with Respect to Sensitizer Stability in Nanocrystalline Dye Solar Cells
Figure 10
Compares the N3 ruthenium
complex, both, in the state of rapid electron recovery (Figure 10(a)) and
in the state of electron extraction via a reasonably high photocurrent flow (Figure 10(b)). While present in the TiO2 interphase, the injected electron
may convert Ti4+ into Ti3+ enabling a back bonding
reaction facilitating a temporary Ti3+(ligand)Ru3+ charge
transfer complex.
