摘要：Three new D–π–A structured organic sensitizers (Dye1-3 ), with various arylamine as donor connected to a 2- phenyl cyanoacrylate BODIPY module, were designed and synthesized for application in dye-sensitized solar cells (DSSCs). The photophysical and electrochemical properties were systematically studied and their performances as sensitizers in DSSCs were comparatively investigated. The structure–property relationship suggests that the rotation freedom of benzene rings in arylamine has a significant influence on the electron-donating abilities, thus effect on the sensitizer's optoelectronic and photovoltaic properties. The DSSCs based on Dye 1 presents the best photovoltaic performance with a Jsc of 8.21 mA cm−2, a Voc of 595 mV, and FF of 0.74, corresponding to an η of 3.61% under AM 1.5 irradiation (100 mW cm−2).
