Molybdenum disulphide (MoS2) nanotube and tungsten oxide (W18O49) nanowire were coated with poly(3-hexylthiophene) (P3HT) and poly(3,4-ethylenedioxythiophene) (PEDOT) by a radio frequency (RF: 13.56 MHz)-rotating plasma-modification method Military Spacecraft Model Kit as alternative counter electrodes for dye-sensitised solar cells (DSSCs).Surface analysis showed the homogenous plasma nanocoating of inorganic nanostructures by P3HT and PEDOT.It was demonstrated that the plasma-modified hybrid platinum-free counter electrodes increased the efficiencies of the DSSCs.The DSSCs based on hybrid nanostructure materials showed a short circuit current density of 9.

49, 7.95, 2.59 and 2.57 mAcm−2 for MoS2/P3HT, MoS2/PEDOT, W18O49/PEDOT and W18O49/P3HT samples, respectively.The plasma nanocoating with the nanostructured materials approach for obtaining hybrid counter electrodes in the photovoltaic action shows Cartridges an alternative route towards cost-effective, green energy conversion.
