- Abstract
- Ti foil for use in dye-sensitized solar cells (DSSCs) is treated in a HNO 3-HF solution. With the exception of cleaning, no additional pre- or post-treatment is performed. This surface-treatment method simultaneously improves electrical and optical behavior, resulting in a highly increased performance in terms of all figures of merit: V oc, J sc, FF, and power conversion efficiency. An overall efficiency of 9.20% can be achieved by use of such HNO 3-HF-treated Ti substrates in DSSCs. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
