(a) J-V characteristics of P25-, HRT-1- and Dyesol-T-based DSCs. Cells were illuminated at an intensity of 100 mW cm−2 with a spectrum approximately AM 1.5 G and an active area of 0.16 cm2; inset: incident photon to current conversion efficiency (IPCE) curves of P25-, HRT-1- and Dyesol-T-based DSCs. (b) diffuse reflectance spectra of P25, HRT-1 and Dyesol-T films. Impedance spectra of DSCs containing P25, HRT-1 and Dyesol-T photoanodes measured at Voc under illumination of 100 mW cm−2: (c) Nyquist plots, with the inset showing the equivalent circuit, and (d) Bode phase plots.
