An Unsymmetrical, Push–Pull Porphyrazine for Dye-Sensitized Solar Cells

Abstract

An unsymmetrical, push–pull porphyrazine derivative bearing an isoindole-4-carboxylic acid moiety (TT112) is synthesized and incorporated in a dye-sensitized solar cell (DSSC). The device, which constitutes the first example of a porphyrazine-sensitized solar cell, exhibits a maximum power conversion efficiency of 3.4 %.
