Enhanced photovoltaic performance of dye-sensitized solar cells using TiO2-graphene microplatelets hybrid photoanode
Mehmood, Umer; Harrabi, Khalil; Hussein, Ibnelwaleed A.; Ahmed, Shakeel ( IEEE Electron Devices Society , 2016 , Article)Hybrid photoanodes for dye-sensitized solar cells (DSSCs) were prepared by simple addition of graphene (GR) microplatelets to TiO 2 nanoparticulate paste. Transmission electron microscopy was used to confirm the presence ... -
Enhanced photovoltaic performance with co-sensitization of a ruthenium(ii) sensitizer and an organic dye in dye-sensitized solar cells
Mehmood, Umer; Hussein, Ibnelwaleed A.; Harrabi, Khalil; Tabet, Nouar; Berdiyorov, G. R. ( Royal Society of Chemistry , 2016 , Article)Co-sensitization is demonstrated to be an effective technique to enhance the efficiency of dye-sensitized solar cells, where an efficiency of 9.23% is achieved by mixing N3 and RK-1 dyes. The assembled solar cells are ...
