A way to achieve a high‐efficiency dye‐sensitized solar cell is to combine an n‐type TiO 2 ‐based photoanode with a p‐type photocathode in a tandem configuration. The development of an efficient photocathode is, at present, the key target. We have optimized the NiO, I 3 − /I − p‐DSSC system to obtain record photocurrent, giving 64% incident photon‐to‐current conversion efficiency (IPCE) and 5.48 mAcm −2 J SC .
