Abstract

This paper reports a rapid (5 min), low temperature (120 �C) method to platinize the counter electrodes
of dye-sensitized solar cell (DSC) devices. This new method uses aqueous solutions and is based on chemical
bath deposition of an activating Pd layer followed by Pt only using H2 gas as the reductant. This
method has been tested on flexible, plastic substrates (indium tin oxide-coated polyethylene terephthalate
or polyethylene naphthalate, ITO-PET or ITO-PEN, respectively). We report device efficiencies up to
7.2% on ITO-PET which is comparable to devices made using high temperature (400 �C) processing on
rigid, fluoride-doped tin oxide (FTO) glass counter electrodes. The method is scalable and suitable for continuous
roll-to-roll production.
