dc.description.abstract | 在此研究中,我們主要討論如何有效的改善poly (3-hexylthiophene) (P3HT)與二氧化鈦奈米桿(TiO2 nanorods)混摻製成有機太陽能電池的效率。混摻太陽能元件效率受到材料分散性、相容性、電子遷移率以及介面能階匹配度等因素之影響,因此我們藉由研究高分子以及無機奈米粒子材料的表面改質,來提升太陽能電池元件的效率。我們透過新合成出低能階的寡分子聚合物:PZFDPP、PZDBTZ以及PZFTBT用做於改質二氧化鈦奈米桿的表面並應用在混摻太陽能電池上,這些寡聚物能階分別為1.2eV、1.6eV以及1.6eV,由置換成TiO2-PZFDPP材料的電子遷移率結果可以明顯的發現,相較於未改質的二氧化鈦電子遷移率自1.1X10-4cm2/Vs 增加到1.8X10-4cm2/Vs。最後,針對反式太陽能電池元件有進一步的設計成果,利用混摻的特色與反式元件較為適合的結構模式,提出一套適合二氧化鈦混摻P3HT的太陽能元件系統,並配合改質之二氧化鈦奈米桿之使用,成功的讓太陽能電池元件效率由未改質的0.42%提升至1.2%。並且針對此研究成果的結構做差異性的探討,了解有效增加電荷傳輸能力的原因與材料間能階的匹配性有關。 | zh_TW |
dc.description.abstract | Our research focuses on the improvement of power conversion efficiency (PCE) of poly (3-hexylthiophene) (P3HT)/TiO2 nanorods hybrid organic solar cell. We studied the effect of different surface ligands on the efficiency of P3HT/TiO2 nanorods hybrid solar cells.
Three conducting oligomeric surface modifiers made by coupling 4, 5–diaza–9, 9’-spiro bifluorene with diketo pyrrolopyrrole (PZFDPP), bithiazole (PZFBTZ), and thieny 1-2, 1, 2-benzothiadiazole (PZFTBT) were synthesized. They exhibit low energy gap of 1.2 eV, 1.6 eV, and 1.6 eV for PZFDPP, PZFBTZ, and PZFTBT respectively. They can form cascade bandgap between P3HT and TiO2 to facilitate the transport of charge carriers. PZFDPP modified TiO2 has the highest electron mobility of 1.8X10-4cm2/Vs as compared with 1.1X10-4cm2/Vs of unmodified TiO2. The surface modified TiO2 was mixed with P3HT to fabricate invert solar cells. The PZFDPP modified TiO2 exhibits the best performance. Its power conversion efficiency was increased from 0.42% to 1.20% as compared with unmodified TiO2. | en |
