Tungsten disulfide nanoparticles anchored on reduced graphene oxide for dye sensitized solar cell applications

We herein describe hydrothermal method to prepare a hybrid material consisting of tungsten disulfide (WS₂) nanoparticles anchored onto reduced graphene oxide (rGO) sheets. Synthesized materials have been characterized for structural, compositional and optical properties by different techniques. Results show that WS₂ nanoparticles are uniformly anchored ontoas well as in between the surface of rGO which helps to inflate the exfoliation of rGO stacked layers. Thus, the rGO/WS₂ hybridcan be used as counter electrode (CE) in dye sensitized solar cells (DSSCs).
