TL;DR: DSSCs formed using the composite CEs show improved performance compared to conventional Pt thin film electrode (Std Pt) and unsupported Pt NPs, and the better catalytic activity of these composite materials is also reflected in the stronger I(-)(3) reduction peaks in cyclic voltammetry scans.

TL;DR: The dye-sensitized solar cells (DSSCs) as mentioned in this paper can be considered to be electrochemical devices consisting of a photoanode which has a thick film of a wide band gap oxide semiconductor, typically coated on a transparent conductive oxide (TCO) glass substrate, with TiO2 being sensitized with adsorbed dyes that absorb visible light.
Journal ArticleDOI
Plasma modified flexible bucky paper as an efficient counter electrode in dye sensitized solar cells
TL;DR: In this article, the bucky papers (BPs) were irradiated with microwave plasma, created using a mixture of Ar (1%) and H2 (99%) gases, for two hours.
