| 計畫名稱 | 高值化學品技術開發與應用四年計畫 | | 論文名稱 | Polythiophene derivative comprising carbazoles as pendant groups for polymer solar cell applications | | 論文類型 | 期刊 | | 發表處 | Thin Solid Films, 519(2011)5264-5269 | | 發表人 | 鄭如忠、蘇文烱 | | 發表日期 | 100/05/31 | | 國家 | 國外 | | 內容摘要 | We have prepared a polythiophene coplymer (CzPh-PT) containing 9-position substituted carbazoles as bulky pendants and investigated its application in polymer solar cell (PSC). Electrochemical study presented that the onset oxidation potential positively shifted 0.47 eV for CzPh-PT in comparison with that of poly(3-hexyl thiophene). By incorporating the bulky substituent of CzPh-PT, the effective conjugation length can be curtailed, and consequently a lowered HOMO energy level (-5.38 eV) was acquired. Thispromises better air stability and a high open circuit voltage (Voc) for thePSC. |
