Paper Title:
Tandem Dye-Sensitized Solar Cells Consisting of Floating Electrode Supported by Non-Conductive Glass Mesh
  Abstract

A tandem dye-sensitized solar cell consisting of two electrodes in one cell is reported. The tandem cell (Cell TAN GF) has a floating electrode (bottom cell) and a TiO2 electrode prepared on a F doped SnO2 glass (top cell). The floating electrode is a flexible and self-standing composite film consisting of a porous titania/dye layer supported by a glass mesh. The Incident Photon to Current Conversion Efficiency (IPCE) curve for the Cell TAN GF had two peaks corresponding to visible absorptions of the two dyes. The open circuit voltage (Voc) of the Cell TAN GF (0.82 V) was higher than that of the corresponding single cell (0.6-0.64 V). These results demonstrated that the Cell TAN GF has a potential for tandem cells. The Voc of Cell TAN GF was almost the same as that of Cell TAN (0.88 V) in which the glass mesh was replaced by a conductive stainless steel mesh having a protective layer, leading to the conclusion that a conductive layer is not necessarily needed.
