摘要註:	本研究以Stille coupling reaction成功合成二種含苯並二噻吩-苯并噻二唑分子衍生物給體-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。本論文分成三部份，第一部分為合成太陽能電池元件構造層材料：活性層(ative layer)材料。第二部分利用紅外線光譜（FT-IR）料之分子量及其聚合分佈指數值 (PDI)，以紫外-可見光光譜 (UV- Vis)及螢光光譜 (PL)觀察光電材料之光學性質及能隙後，可由循環伏安圖譜 (CV)估算出光電材料之最高滿軌域 (HOMO)能量及最低空軌域 (LUMO)能量，並以熱示差掃瞄卡計 (DSC)分析出材料之熱性質。第三部分使用上述合成的光電材料應用於高分子本體異質結太陽能電池元件，並進行光電轉換效率的量測。並討論以不同Polymer：PCBM 混摻比例和不同退火溫度對其太陽能電池元件效率之影響。合成之P1、P2分別具有1.82 eV和1.80 eV的低能隙，分別具有350-900 nm的寬吸收範圍。在P1:PCBM混摻比例為1:2及退火溫度為150℃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3.34 mA/cm2，FF值36.1% 及光電轉換效率0.59％。在P2:PCBM混摻比例為1:1及退火溫度為175℃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3.69 mA/cm2，FF值40.8%及光電轉換效率0.81％。 We have sucessfully synthesized two donor-acceptor alternating conjugated polymers P1 and P2 containing benzodithiophene and benzothiadiazole derivatives as the donor and acceptor units, respectively, for the donor materials of the active layer by Stille coupling reaction. Our study was divided into three parts. The first part was to synthesize the donor materials of both types: P1 and P2. Subsequently, all synthesized optoelectronic materials were confirmed with FT-IR and NMR analyses. Molecular weights and polydispersity indices (PDI) were obtained by GPC. Optical properties were observed with UV-vis and photoiuminescence (PL) spectra. On the other hand, by the combination of band gap values from UV-vis spectroscopies with the oxidation-reduction potential values from cyclic voltammetry (CV), highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) values of both optoelectronic materials could be estimated. In addition, thermal properties of both synthesized materials were analyzed with thermogravimetric (TGA) and differential scanning calorimetry (DSC). The third part was the 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. We studied the effects of 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. Both P1、P2 exhibits a low band gap of 1.82 eV and 1.80 eV and broad absorption band from 350 to 900 nm, which allows it to absorb more available photons from sunlight. The bulk heterojunction polymer solar cell incorporating P1 and PCBM at a blend ratio of 1:2 and annealing temperature 150℃ exhibited the highest short-circuit current density of 3.34 mA/cm2 and a power conversion efficiency of 0.59%. The bulk heterojunction polymer solar cell incorporating P2 and PCBM at a blend ratio of 1:1 and annealing temperature 175℃ exhibited the highest short-circuit current density of 3.69 mA/cm2 and a power conversion efficiency of 0.81%.
