Electrochemically Reduced Graphene Oxide Multilayer Films as Efficient Counter Electrode for Dye-Sensitized Solar Cells
We report on a new counter electrode for dye-sensitized solar cells (DSCs), which is prepared using layer-by-layer assembly of negatively charged graphene oxide and positively charged poly (diallyldimethylammonium chloride) followed by an electrochemical reduction procedure. The DSC devises using the heteroleptic Ru complex C106TBA as sensitizer and this new counter electrode reach power conver...
متن کاملFlexible and platinum-free dye-sensitized solar cells with conducting-polymer-coated graphene counter electrodes.
Dye-sensitized solar cells (DSSCs) have emerged as a high-efficiency, low-cost alternative to solid-state silicon solar cells. Typically, DSSCs are composed of a mesoporous titania nanocrystal electrode on a transparent conductive oxide (TCO) substrate with ruthenium-based sensitizers on the titania nanocrystals, platinum on the TCO substrate as a counter electrode, and iodine/iodide electrolyt...
متن کاملDually functional, N-doped porous graphene foams as counter electrodes for dye-sensitized solar cells.
A series of nitrogen-doped porous graphene foams (NPGFs) have been prepared by hydrothermally treating a mixed solution of graphite oxide (GO) and ammonia. The NPGFs are used as the counter electrode (CE) material for dye-sensitized solar cells (DSCs) in conjunction with the conventional iodide-based electrolyte and the recently developed sulfide-based electrolyte. Tafel-polarization tests and ...

متن کاملNitrogen-doped graphene foams as metal-free counter electrodes in high-performance dye-sensitized solar cells.
Owing to their low-cost production, simple fabrication, and high energy conversion efficiency, dye-sensitized solar cells (DSSCs) have attracted much attention since Oregan and Gr tzel s seminal report in 1991. A typical DSSC device consists of a dye-adsorbed TiO2 photoanode, counter electrode, and iodide electrolyte. The counter (cathode) electrode plays a key role in regulating the DSSC devic...
