Perylenediimides are ideal candidates for the substitution of fullerene derivatives as electron acceptors in bulk heterojunction organic solar cells due to their extremely intense light absorbance, high mobility and excellent photochemical stability.
Phthalocyanines (Pcs) are promising candidates for photon collectors the near-infrared region of solar spectrum in dye cells (DSC). Using two new Pc sensitizers, differing only their Zn or metal-free center, we discuss behaviour dyes as sensitizers DSC, and influence on cell performance, comparison with standard N719 dye, at identical electrolyte conditions. Based separate identification recombination resistance energy levels titania by impedance spectroscopy, determine rates also map...
Phthalocyanines are among the most promising of efficient molecules for commercial application in dye sensitized solar cells due to their extremely intense red absorbance and excellent photochemical stability.
Graphene exfoliation upon tip sonication in o-dichlorobenzene (o-DCB) was accomplished. Covalent grafting of (2-aminoethoxy)(tri-tert-butyl) zinc phthalocyanine (ZnPc) to exfoliated graphene sheets then achieved. The newly formed ZnPc–graphene hybrid material found be soluble common organic solvents without any precipitation for several weeks. Application diverse spectroscopic techniques verified the successful formation material, while thermogravimetric analysis revealed amount ZnPc loading...
