摘要:
A paste composition comprises a dye containing a novel oligomeric compound with improved dispersion performance. The oligomeric compound comprises a tail structure consisting of hydrophilic and hydrophobic blocks and an amine or imidazole head structure. The paste composition can be used to prepare a semiconductor electrode of a solar cell. A semiconductor electrode produced using the paste composition and a solar cell fabricated using the semiconductor electrode exhibit greatly improved power conversion efficiency and superior processability.
