    摘要註: 本研究以Stille coupling reaction成功合成二種含二噻吩并噻咯-苯并呋咱分子衍生物給體-受體交錯型共軛高分子P1、P2,並當作活性層之電子給體材料。合成之P1、P2分別具有1.41 eV和1.38 eV的低能隙,分別具有300-1100 nm的寬吸收範圍。在鑑定方面透過FT-IR、1H NMR及13C NMR來做確認。而材料之光電特性可利用紫外-可見光光譜 (UV- Vis)及螢光光譜 (PL)以及循環伏安圖譜 (CV)來做研究。最後將合成之高分子材料製備成本體異質結太陽能電池元件,並探討不同混摻PCBM的比例及退火溫度對元件效率之影響。在P1:PCBM混摻比例為1:2及退火溫度為125°C時,以P1和PCBM為活性層之本體異質結太陽能電池有最佳的短路電流密度3.77mA/cm2,FF值37.1% 及光電轉換效率0.95%。在P2:PCBM混摻比例為1:2及退火溫度為150°C時,以P2和PCBM為活性層之本體異質結太陽能電池有最佳的元件表現,短路電流密度4.13mA/cm2,FF值38.5%及光電轉換效率1.22%。 We have sucessfully synthesized two donor-acceptor alternating conjugated polymers P1 and P2 containing dithienosilole and benzofurazan derivatives as the donor and acceptor units, respectively, for the donor materials of the active layer by Stille coupling reaction. Both of them exhibited the intramolecular donor-acceptor characteristic and displayed a panchromatic absorption ranging from 300 to 1000 nm and P1 have an ideal bandgap of 1.41 eV, and P2 is 1.38 Ev. The structure of the polymers were confirmed by FT-IR, 1H NMR, and 13C NMR. Optoelectronic properties of the polymer were investigated and observed by UV-vis, photoluminescence spectrum, and cyclic voltammogram. Finally we were application of both of the synthesized materials in the active layers of polymer bulk heterojunction photovoltaic (BHJ) solar cells and the measurements of power conversion efficiency in different weight ratios of the Polymer : PCBM blends and different annealing temperatures on the performance of polymer solar cells using the blend (Polymer : PCBM) as active layers. The bulk heterojunction polymer solar cell incorporating P1 and PCBM at a blend ratio of 1:2 and annealing temperature 125℃ exhibited the highest short-circuit current density of 3.77 mA/cm2 and a power conversion efficiency of 0.95%. The bulk heterojunction polymer solar cell incorporating P2 and PCBM at a blend ratio of 1:1 and annealing temperature 150℃ exhibited the highest short-circuit current density of 4.13 mA/cm2 and a power conversion efficiency of 1.22%.
