A series of Lindquist-type polyoxometalate (POM)-porphyrin hybrids were designed to study the effect of POMs on the performance of dyes. The electronic transition properties, absorption spectra, and photovoltaic performance of these hybrids for n-type DSSCs were studied. The absorption spectra of dyes 2-5 exhibit broader and larger absorptions than synthesized dye 1. Further analysis of electronic transition properties indicates that the introduction of POM makes the charge transfer process longer and stronger. Moreover, the photovoltaic performances of these designed dyes are suitable for efficiency n-type DSSCs. These designed dyes can be used as shortlist dyes for n-type DSSCs.
