Preparation of Flexible Pt Counter Electrode on In-dium-doped Tin Oxide Coated Polyethylene Naphthalate for Dye-sensitized Solar Cells

摘要：

Flexible Pt counter electrode (CE) was prepared by a simple and fast electroless deposition on indiumdoped tin oxide coated polyethylene naphthalate (ITOPEN) plastic substrate for dye-sensitized solar cells (DSCs). The obtained Pt CE shows a high electrocatalytic activity for triiodide reduction and a low charge transfer resistance of 0.58 Ω·cm2. The assembled DSC exhibits an overall energy conversion efficiency of up to 4.53％, which is comparable to that of the DSC with sputtered Pt CE (4.74％). The present results indicate that the electroless deposition is an effective approach to prepare plastic Pt CEs as an alternative of the sputtering technology.
