Efficient sinter-free nanostructure Pt counter electrode for dye-sensitized solar cells†
Abstract
In this study, we report a novel strategy to make nanostructure Pt counter electrodes for dye-sensitized solar cells (DSSCs). A platinum hydrosol was used as a precursor of Pt nanoparticles and electrochemically deposited onto FTO conductive glass without a sinter, and exhibited excellent catalytic performance for use as counter electrodes for N719-based DSSCs.
