説明
The light-harvesting efficiency of polymer solar cells based on a conjugated polymer (p-type semiconductor) and a fullerene derivative (n-type semiconductor) can be effectively improved by incorporating near-IR dye molecules with bulky axial groups. Further improvement in the photocurrent can be easily obtained by incorporating different dye molecules that have complimentary absorption bands. Transient absorption studies have shown that all the primary processes in the dye sensitization proceed with almost 100% efficiency and that most of dye molecules are located at the p-n junction. Such interfacial segregation of dye molecules is partly due to crystallization of polymer matrix, which would expel dye molecules into the p-n junction, and partly due to intermediate surface energy of dye molecules between polymer and fullerene, by which dye molecules would serve as a surfactant in polymer/fullerene blends.<br>
