Donor-π-Conjugated Spacer-Acceptor Dye-Sensitized Solid-State Solar Cell Using CuI as the Hole Collector

Figure 5

Red and blue lines correspond to the - characteristics of the DSSCs with 15 μm thick TiO₂ films dyed using 0.3 mM of MK-2 in acetonitrile/t-butyl (1 : 1 / ratio) and 0.3 mM of MK-2 in toluene, respectively (active cell area 0.25 cm² and measured under simulated 100 mW cm^-2 AM 1.5 illumination).
