| Abstract: | Carbon nanotubes (CNTs) have been widely considered as one of the promising candidates for replacing fluorine‐doped tin oxide (FTO)/platinum (Pt) electrodes to reduce the fabrication cost of dye‐sensitized solar cells (DSSCs). Here, we report that a bilayer transparent film containing N‐doped CNTs (which are highly catalytic) and normal CNTs (which are highly conductive) as a counter electrode in DSSCs results in efficiencies up to 2.18 %, yet still maintains a good transparency with a transmittance of approximately 57 % at 550 nm. |
