The impact of a TiO/r-GO composite material on the performance of electron transport electrodes of dye sensitized solar cells.

In dye sensitized solar cells, the role of the electron transport layer is crucial because it makes it easier for photo-generated electrons to get from the dye to the external circuit. In DSSCs, the utilization of TiO is likely to be given preference in the production of electron transport electrodes due to its notable characteristics such as its expansive surface area, porosity, and capacity to scatter light. Nevertheless, the presence of heterogeneity within the mesoporous structure increases the likelihood of TiO aggregation, which subsequently diminishes the beneficial impact of TiO on the performance of DSSCs.
