Theoretical Study of Gallium Phthalocyanine Dimer-Fullerene Complex for Photovoltaic Device
نویسندگان
چکیده
Geometry and electronic structures of gallium phthalocyanine dimer and fullerene molecules were investigated by theoretical calculation. The highest occupied molecular orbital was localized on the donor site, and the lowest unoccupied molecular orbital were localized on accepter site. The present results indicate that high conversion efficiency would be expected when phthalocyanine dimers were used as solar cell materials.

متن کاملSemitransparent organic photovoltaic cells with laminated top electrode.
We demonstrate semitransparent small molecular weight organic photovoltaic cells using a laminated silver nanowire mesh as a transparent, conductive cathode layer. The lamination process does not damage the underlying solar cell and results in a transparent electrode with low sheet resistance and high optical transmittance without impacting photocurrent collection. The resulting semitransparent...

We have fabricated poly(3-hexylthiophene) (P3HT)/copper phthalocyanine (CuPc)/fullerene (C60) ternary blend films. This photoactive layer is sandwiched between an indium tin oxide (ITO)/poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT/PSS) photoanode and a bathocuproine (BCP)/aluminium photocathode. The thin films have been characterized by atomic force microscope (AFM) and ultra...
متن کاملSynthesis of mesogenic phthalocyanine-C60 donor–acceptor dyads designed for molecular heterojunction photovoltaic devices
A series of phthalocyanine-C(60) dyads 2a-d was synthesized. Key steps in their synthesis are preparation of the low symmetry phthalocyanine intermediate by the statistical condensation of two phthalonitriles, and the final esterification of the fullerene derivative bearing a free COOH group. Structural characterization of the molecules in solution was performed by NMR spectroscopy, UV-vis spec...
متن کاملInteractions of Deferasirox as a Chelating Agent with Al and Ga Cations: A Theoretical Study on the [M(DFX)2]3- Nanostructures
A theoretical study was performed to evaluate the defersirox potency to chelate aluminum (Al) and gallium (Ga) as the toxic metals in biological systems. Deferasirox as an important class of chelators, which binds to the metallic center with the ratio of 1:2, is used to remove the toxic metals in the case of iron overload disease. The effects of water and DMSO as the solvent on the electronic n...
