| Summary: | 碩士 === 大同大學 === 化學工程學系(所) === 92 === 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.
