摘要

The fabrication of highly efficient plastic-substrate dye-sensitized solar cell (Pla-DSC) sub-module was conducted by using the roll press method at room temperature. As a result, a 5cm-square Pla-DSC sub-module with 6.5 % efficiency, which is one of the best efficiencies among Pla-DSC sub-modules, was developed. A newly developed light-scattering counter electrode composed of the TiO_2 large-particle-layer over Pt sputtered Ti foil as well as the cosensitization of black dye and organic dye D131 was applied to improve the efficiency of 5mm-square Pla-DSC mini cell. The efficiency improved from 7.8 % up to 9.1 %, which is the world record among Pla-DSC mini cells. Then, a large-size TiO_2 photoelectrode was prepared by the doctor blade coating of TiO_2 paste and the following roll press at 100 MPa at room temperature. The exfoliation of TiO_2 film from ITO/PEN substrate under the roll press was the problem to solve. A newly designed alcohol-mixture solvent for TiO_2 paste suppressed the defoliation of TiO_2 film from the substrate. In addition, the current-collecting Ag grid and its protecting layer on Ag grid against iodine corrosion were fabricated over the ITO/PEN substrate to improve the cell efficiency of Pla-DSC sub-module. A durable methoxy-propionitrile (MPN) electrolyte solution was utilized. Finally, a highly efficient and durable Pla-DSC sub-module was successfully fabricated.
