Mehmood U.; Harrabi K.; Hussein I.A.; Shanmugam N.; Mekki A.; Mekki M.; McLachlan M.A.... more authors ... less authors ( Springer Verlag , 2019 , Article)The objective of this study is to investigate the stability of the active layer of polymer solar cells from the effect of UV–visible light irradiation using different conditions with respect to time. The active layers were ... -
Effect of outdoor temperature on the power-conversion efficiency of newly synthesized organic photosensitizer based dye-sensitized solar cells
Mehmood U.; Malik M.I.; Ul Haq Khan A.; Hussein I.A.; Harrabi K.; Al-Ahmed A.... more authors ... less authors ( Elsevier B.V. , 2018 , Article)In this work, organic photosensitizer has been synthesized for dye-sensitized solar cells (DSSCs). The solar cells then fabricated have been characterized by photocurrent-voltage characteristics and electrochemical impedance ... -
Improving the efficiency of dye sensitized solar cells by TiO2-graphene nanocomposite photoanode
Mehmood U.; Ahmed S.; Hussein I.A.; Harrabi K. ( Elsevier B.V. , 2015 , Article)Nanocomposite photoanodes were prepared by addition of graphene (GR) micro-platelets to TiO2 nanoparticulate paste. TiO2/graphene based DSSCs were fabricated using Z907 photosensitizer. Transmission electron microscope was ...
