Tandem Dye-Sensitized Solar Cells Fabricated on Glass Rod without Transparent Conductive Layers

摘要

A tandem dye-sensitized solar cell was fabricated on a glass rod without a transparent conductive oxide layer (TCO-less GR-DSSC). Two model dyes having λ_(max)= 429 nm (Dye Ⅱ) and λ _(max)= 646 nm (Dye Ⅰ) respectively were used to examine the potential of the cell. The incident photon to current conversion efficiency (IPCE) curve of the TCO-less GR-DSSC had two peaks at around 490 and 600-650 nm. Open circuit voltage (V_(oc)) of the TCO-less GR-DSSC was 1.13V which was the sum of the V_(oc) (0.57V) of each single cell. The results strongly demonstrate that the cell has a tandem character.
