“…In recent years, porphyrins have drawn a lot of attention for use as sensitizers in DSSCs due to their vital roles in natural photosynthetic systems 22,23 and strong absorption in the visible region, 24 as well as their optical, 25 photophysical 26 and electrochemical properties 27 which are readily tuned by peripheral substitutions. Typically, it was reported that a "push-pull" type porphyrin with a donor-p conjugated unit-acceptor (D-p-A) structure [28][29][30] would achieve high light-to-electricity conversion efficiency (h). For example, recently the DSSC based on YD-o-C8 has remarkably achieved an overall photoelectric conversion efficiency of 12.3% with a cobalt-based redox electrolyte.…”

“…Most recently, during the preparation of our manuscript Hung and Diau et al [18] reported a new "2D-p-2A" type porphyrins for use in stable and cost-effective DSSCs. Our group [19] previously also showed the synthesis of simple and efficient porphyrin dyes with a best h of 3.05% realized under our experiment condition.…”

a b s t r a c tThree p-A-porphyrins containing long alkoxyl chains attached to the ortho position of phenyl ring and a phenyl carboxylate acid or acrylic acid at the meso position of porphyrin were synthesized. All compounds were characterized by 1 H NMR and mass spectrometry. Optical and electrochemical properties were also obtained. The photovoltaic properties of these p-A-porphyrins were examined for the first time and sensitizers N-1 and N-3 achieved comparable light to electricity conversion efficiencies: 3.94% for N-1 and 4.14% for N-3. However, preparation of N-1 required simple and cost-effective synthesis which made it a promising candidate for the future practical DSSC applications. The low efficiency conversion of N-2 was well explained by the amount of dye loading, IPCE and EIS.

Intrinsic defect of electronic structure for the chlorine‐type porphyrin 1, which was synthesized for use in dye‐sensitized solar cell (DSSC), is found by theoretical calculation including density functional method (DFT), time‐dependent DFT, and C+/C− function. It is believed that the limited cell performance obtained by using dye 1 as the sensitizer is due to the existence of this electronic defect. To avoid this defect, a series of novel molecules with electron deficient π bridge were designed. The subsequent theoretical calculation indicated that the electron deficient π bridge in the newly designed molecule is quite effective in offsetting the electronic defect observed for dye 1. The parameters for the designed molecules closely associated with open‐circuit voltage and short‐circuit current density including dipole moment of dye vertical to the surface of semiconductor and light‐harvesting efficiency were then evaluated. By comparing these parameters of designed dyes with those of dye 1, we can predict that the DSSC based on dye 4 (2, 6‐cyan benzoic acid as anchoring group) should possess enhanced performance, which would be a valuable theoretical guidance for the practical work. © 2013 Wiley Periodicals, Inc.
