Abstract

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.
