Fig. 11. (a) Measured JV-characteristics at AM 1.5G illumination for best performing solar cells sensitized with [Fe(cpbmi)2](PF6)2 (reference), [Fe(cpbmi)(dtapbmi)](PF6)2 and [Fe(cpbmi)(daapbmi)](PF6)2. (b) Corresponding Incident-photon-to-current-conversion efficiency (IPCE) spectra (solid lines), and integrated photocurrent density Jsc (dashed lines).
