Thermally stable amorphous polymeric semiconductors containing fluorene and thiophene for use in organic photovoltaic cells |
| 초록 |
We report amorphous polymeric semiconductors containing fluorene and thiophene, specifically poly(2-(5-(9,9-dibutyl-9 H-fluoren-2-yl)-3-hexylthiophen-2-yl)-5-(3-hexylthiophen-2-yl)thieno[3,2-b]thiophene) (P1) and poly(2-(5-(9,9-dibutyl-9 H-fluoren-2-yl)-4-hexylthiophen-2-yl)-5-(4-hexylthiophen-2-yl)thieno[3,2-b]thiophene) (P2), for use as electron donor materials in organic photovoltaic cells. A maximum power conversion efficiency of 1.8% and a high open circuit voltage of 0.97 eV were obtained from the P2:PCBM blend. Morphological and structural analysis of the polymer:PCBM blend films demonstrated that the range of possible side chain arrangements produced distinctly different nanomorphologies and, therefore, different thermal stabilities of the resulting devices. P2 was characterized by long alkyl chain spacings that yielded a uniformly amorphous morphology and steady photovoltaic performance, even at elevated temperatures. |
