摘要

本研究主要在於製備有機/無機複合材料，並將其應用於光電元件。以in-situ polymerization方式，將3-己烷基噻吩和有機黏土(organophilic-clay)用無水的的FeCl3進行氧化偶合反應，製備得聚(3-己烷基噻吩)/有機黏土複合材料(P3HT/organophilic in-situ composite).經由X-ray繞射推論有機黏土於P3HT中達插層級分散。將rm-P3HT與有機黏土進行in-situ聚合製備成光電壓電池，發現隨著有機黏土含量增加，短路電流也隨著增加。最佳元件－Au/65HT-P3HT with 10 wt% of organophilic clay treated with poly(propylene glycol)–bis (2-aminopropyl ether) in-situ composite)gent in-situ composite/Si/Al，閉環電流和開環電壓，會有逐漸提升的趨勢，在48 mW/cm2白光照射下能量轉換效率達到0.63%。
poly(3-alkylthiophenes)(P3AT)－poly(3-hexylthiophene)(P3HT)、poly(3-octylthiophene)(P3OT)和poly(3-decylthiophene)(P3DT)三種之位置規則度（96～97％）聚（3-烷基噻吩）材質進行光伏特電池的特性探討，結果發現P3OT在以矽晶片為基材之太陽電池的特性較佳，其fill factor為0.38，能量轉移效率（η）為0.21％。因而就以P3OT作為主要的材質，進行濃度效應、溶液效應、基材表面改質和奈米材料－TiO2的添加。但在ITO為基材的元件，進行光電壓電池特性測試，其能量轉移效率都在10 - 3～10 – 4%間。
在位置規則度方面，最佳元件－Au/P3OT/TiO2 (365nm)/Si/Al的閉環電流和開環電壓，有逐漸提升的趨勢，在48 mW/cm2白光照射下能量轉換效率達到0.74%。矽晶片經n-hexadecyl mercaptan的親油性處理，讓polymer成膜性更佳，Au/1 wt% of 97%HT-P3OT/Si/Al的元件，在 48 mW/cm2白光照射下，效能可提升至0.67％。

Studies on the synthesis and applications of poly(3-hexylthiophene)/inorganic nanoparticle on photovoltaic cell. By in-situ polymerization, P3HT/organophilic-clay composite were synthesized by the oxidation coupling reaction of 3-hexylthiophene with anhydrous FeCl3 at room temperature. By X-ray diffraction analysis, the organophilic-clay was exfoliated in the P3HT matrix. It is found that short-circuit photocurrent density and open-circuit photovoltage of PV cells increase with increasing the content of organophilic-clay. The optimal power conversion efficiency of PV cell fabricated by Au/65HT-P3HT with 10 wt% of organophilic clay treated with poly(propylene glycol)–bis (2-aminopropyl ether) in-situ composite/Si/Al can be achieved 0.63% under white light illumination of 48 mW/cm2.
The characteristic of photovoltaic cell fabricated with regioregular poly(3-akylthiophenes) (P3AT)- poly(3-hexylthiophene) (P3HT), poly(3-octylthiophene) (P3OT) and poly(3-decylthiophene) (P3DT) with 96~97% HT-HT couplings have been investigated. The optimal power conversion efficiency of single layer photovoltaic cell-Au/P3OT/Si/Al can be achieved 0.21% under white light illumination of 48 mW/cm2. The effects of solvent, solution, substrate improvement and adding nanoparticle-TiO2 have been investigated. The power conversion of ITO/P3AT/Al PV cell was about 10 - 3~10 - 4%.
The power conversion efficiency of Au/P3OT/TiO2 (365 nm)/Si/Al double layers PV cell can be achieved 0.74% under white light illumination of 48 mW/cm2. The power conversion efficiency of Au/ P3OT/Si/Al photovoltaic cell parameters can be achieved 0.67% for silicon substrate treated with n-hexadecyl mercaptan.
