Dye‐sensitized solar cells (DSSCs) comprising chemically synthesized nanorods and nanoparticles are investigated. In identical circumstances, except for the charge‐collection efficiency, nanorod‐based DSSCs show improved photovoltaic properties (6.2 % versus 4.3 % for NP‐based DSSCs) owing to the characteristics of slightly enhanced electron transport and predominantly degraded charge recombination, compared with nanoparticle‐based DSSC.
