Low-Temperature Hydrogen Plasma Reduction of Graphene Oxide Counter Electrodes for Printed Dye-Sensitized Solar Cells
Original language description
In this work, solution-processable graphene oxide (GO) dispersions were used for the simple preparation of thin GO layers (50 nm thickness), which were reduced by low-temperature hydrogen plasma. Hydrogen plasma reduction (ideal treatment time 8 sec) led to a decrease of oxygen-containing groups and consequently, in the transformation of sp3-carbon oxidized domains to preferable sp2-carbon aromatic domains in rGO layers (XPS). GO and rGO layers were used as counter-electrodes (CEs) in printed dye-sensitized solar cells (DSSCs). DSSCs with rGO CEs reached an increased conversion efficiency of 0.9 % compared to DSSCs based on GO CEs with 0.4%. This can be attributed to the higher catalytic activity of plasma reduced rGO CEs in the presence of iodine electrolyte and also lower sheet resistance compared to GO CEs.
