A study on stability of active layer of polymer solar cells: effect of UV–visible light with different conditions
( 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 ... -
A Facile Synthesis of Poly(aniline-co-3-trifluoromethyl aniline) Doped Silver Nanoparticles in Micellar Solution: Its Humidity Sensor Application
( Pleiades Publishing , 2018 , Article)© 2018, Pleiades Publishing, Ltd. Copolymerization of aniline and 3-trifluoromethyl aniline was carried out by in-situ chemical oxidative technique using slow dispersion of silver nanoparticles. The prepared copolymer was ... -
High Excitation Intensity Opens a New Trapping Channel in Organic-Inorganic Hybrid Perovskite Nanoparticles
( American Chemical Society , 2016 , Article)We investigated the excited-state dynamics of CH3NH3PbBr3 perovskite nanoparticles (NPs) and bulk crystals under various excitation intensity regimes using transient absorption spectroscopy. We confirmed the sub-band gap ... -
Improving the efficiency of dye sensitized solar cells by TiO2-graphene nanocomposite photoanode
( 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 ...
