Dye-sensitized solar cells (DSSCs) have taken up broad interest as a promising low-cost solar cell technology since they were ﬁ rst reported on in 1991.1DSSCs use specialized materials for speci ﬁ c cell functions such as photon absorption, charge separation, and charge transport. Figure 1 depicts a simpleenergy diagram of how these devices function. A photon enters the solar cell through a transparent electrode and can be absorbed by a sensitizer, exciting an electron (a), as shown in Figure 1A. Then this electron can be injected into the conduction band of a neighboring semiconductor (b) and di ﬀ use to the current collector (c). The electron can perform work and ﬂ ow to the cathode (d) where it is transferred to an electrolyte or a hole conductor (e). This material can thentransfer an electron to the sensitizer (f), regenerating it and completing the circuit. To optimize these devices and achieve respectable power conversion e ﬃ ciencies ( η , de ﬁ ned as the ratio of power incident on the solar cell to the maximum power produced by the solar cell; see Box 1 for details on solar cell characterization) researchers have looked at ways to (i) maximize light harvesting and (ii) minimize losses due to parasitic electron transfer pathways (v, w, x, y, and z in Figure1B) while also minimizing the overpotentials required to drive the electron transfer in the desired direction .
