Table 2.
Photovoltaic performance of p-DSCs constructed using 1–3. Standard deviations as determined for five devices constructed from the same batch of cells for JSC, VOC, FF and η are provided in parenthesis. JSC is the short-circuit current density at the V = 0 intercept, VOC is the open-circuit voltage at the J = 0 intercept, FF is the device fill factor, η is the power conversion efficiency; IPCE is the monochromatic incident photon-to-current conversion efficiency.
