Solid-state dye-sensitized solar cells, however, it had not been allowed to make good efficiency. Even though it can prevent the leakage and corrosion of electrodes, leading to a decrease in the lifetime and the efficiency of the system, poor pore-filling was the bottle neck. In 2008, Yanagida reported in-situ photoelectrochemical polymerization (PEP) technique with high efficiency. They showed 2.9 % of power conversion efficiency by using bis-3,4-ethylenedioxythiophene (bis-EDOT). It was only successful case since the PEP technique was invented in 1998. Recently, 6 % of power conversion efficiency of PEP-based system was achieved by Ramakrishna, but it was also bis-EDOT-based system. Here, we suggested novel conducting polymers which were EDOT-based monomers having aromatic rings between EDOTs. The designed monomers we synthesized were expected to longer conjugation on their backbones which can enhance the power conversion efficiency of the PEP-based solar cells. |
