Many attempts have been made to integrate energy conversion and storage devices into individual units for highly efficient, light‐weight, portable devices. On page 1840, G. Shen, D. Li, and co‐workers present a stack‐integrated photo‐supercapacitor thin‐film device, which comprises a dye‐sensitized solar cell and a supercapacitor (SC) built on bipolar TiO 2 nanotube arrays. In addition, selective plasma‐assisted hydrogenation treatment of the SC electrodes delivers enhanced SC performance and overall photoelectric conversion and storage efficiency.
