Abstract

A new porphyrin sensitizer, LD31, was designed based on a donor-π-acceptor structure, in which an ethynyl-anthracenyl moiety was inserted between the dioctylaminophenyl group and the porphyrin core in order to extend the π-conjugation of the dye for improved light-harvesting ability. The device made of LD31 exhibited panchromatic spectral features covering the whole visible region and further extending over 800 nm. When combined with an organic dye (AN-4), the performance of the LD31/AN-4 co-sensitized device attained J_SC/mA cm^-2 = 20.3, V_OC/mV = 704, FF = 0.72, and the overall efficiency of power conversion η = 10.3%.
