中文摘要	synthesis, characterization and application of trans-d-b-a-porphyrin based dyes in dye-sensitized solar cells
英文摘要	a series of metal-free trans-d-b-a porphyrin dyes have been synthesized and characterized as photosensitizers for dye-sensitized solar cells (dsscs). these dye molecules contain a porphyrin unit as a pi-bridge, a substituted phenyl group as an electron donor and cyanoacrylic acid or carboxylic acid group as an electron acceptor (anchoring groups). this phenomenon is more pronounced for porphyrins (dye 4 and dye 5) that have conjugated diphenyl aniline at the opposite side of the anchoring group. a solar conversion efficiency of 2.38% has been achieved with a short circuit current (j(sc)) of 7.63 ma/cm(2), an open circuit voltage (v-oc) of 0.613 v and a fill factor (ff) of 51.0% for dye 5 under standard global am 1.5 solar irradiation. results of time-dependent density functional theory (td-dft) calculations on these five organic dyes support the electrochemical data.
