Photovoltaic Properties of Low-Band Gap Polymer Consisting of Alternating Thiophene and Benzothiadiazole Derivatives as a Hole Transport Material for Dye-Sensitized Solar Cells |
| 초록 |
Hole conducting polymer had been the point of issue to improve power conversion efficiencies of DSSCs. In this study, a novel low-band gap conjugated polymer, poly[4,7-bis-(3’,3’-dihepyl-3,4-propylenedioxythienyl)-2,1,3-benzothiadiazole] [Poly(heptyl4-PTBT)] consisting of alternating electron-rich diheptyl-substituted propylene dioxythiophene and an electron-deficient 2,1,3-benzothiadiazole units was synthesized and its solar properties were investigated. The thin film of poly(heptyl4-PTBT) exhibits an optical bandgap of 1.55 eV. Solid state dye-sensitized solar cell with SnO2:F/TiO2/N3 Dye/poly(heptyl4-PTBT)/Pt device was fabricated using poly(heptyl4-PTBT) as a hole transport material. This device exhibits a high power conversion efficiency of 3.1 % under AM 1.5 irradiation (100 mW/cm2). |
