Effects of counter electrodes on photovoltaic performance of allsolid-state TiO2-based dye-sensitized solar cells
In order to analyse the effects of counter electrodes on photovoltaic performance of dye-sensitized solar cells (DSSCs), different electrodes were used as the counter electrodes for all-solid-state TiO2-based DSSCs. An inorganic solid-state electrolyte, CsSnI2.95F0.05, was selected to couple with N719 dye-sensitized TiO2 nanorod arrays to fabricate the DSSCs. Fluorine doped tin oxide transparent conducting glass (FTO), platinum coated FTO (Pt/FTO), graphite coated FTO (graphite/FTO), and graphite coated common glass (graphite/glass) were investigated as the counter electrodes, and the cells composed of the corresponding electrodes above have power-conversion efficiencies of 2.17%, 9.84%, 7.62%, and 3.45%, respectively. Our findings indicate that due to its unique catalytic and conducting properties, graphite can replace both Pt and FTO as a counter electrode to reduce the fabrication cost of all-solid-state TiO2-based DSSCs.
