Nanorod-Based Dye-Sensitized Solar Cells with Improved Charge Collection Efficiency

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 ch...

Zusammenfassung: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.
