本論文先找尋標準P3HT/PCBM有機光伏電池最佳化元件的製程。溶劑處理(solvent annealing)製程可使標準元件維持較高的光電轉換效率(power conversion efficiency)。此製程我們同時探討溶劑和P3HT高分子分子量對於P3HT/PCBM有機光伏電池光電轉換效率及感光層表面形態的影響。
進一步探討了摻雜有機光電小分子或硫化鎘奈米粒對P3HT/PCBM有機光伏電池的影響。發現有機光電小分子的摻雜對光電轉換效率的提昇沒有幫助。然而摻雜硫化鎘奈米粒,會促進P3HT的聚集排列,元件電子與電洞傳輸能力同時被提升,使其光電轉換效率有明顯的從3.24 %增加到4.1 %。
In this thesis, we first look for the optimization process for the fabrication of standard P3HT/PCBM organic photovoltaic devices. By the process of solvent annealing, the standard P3HT/PCBM organic photovoltaic device can maintain higher power conversion efficiency.Meanwhile, we study the effect of different solvents and different P3HT molecular weights on the P3HT/PCBM organic photovoltaic power conversion efficiency and the active layer surface morphology.
In the further of this thesis, we study the influence of doping some optoelectronic small organic molecules or Cadmium Sulfide nanoparticles on the P3HT/PCBM organic photovoltaic device. No enhancement of power conversion efficiency was found when optoelectronic small organic molecules were doped into organic photovoltaics. However, doping Cadmium Sulfide nanoparticles greatly enhances power conversion efficiency of the organic photovoltaics from 3.24 % to 4.1 %, and this can be attributed to the improvement of P3HT aggregation and then improve electron and hole mobilities.
