摘要

本研究使用P3HT、F8T2作為Donor與PCBM作為Acceptor來製作多接面結構的高分子太陽能電池。所製作的元件擁有多種P-N接面，分別為P3HT / PCBM、F8T2 / PCBM與P3HT / F8T2的接面；這種多接面結構的太陽能電池可提升激子的分離效率並提升元件開路電壓，以提高電荷收集效益並改善元件光電轉換效應。並使用原子力顯微鏡、吸收光譜儀、外部量子轉換效率和光學顯微鏡來解釋主動層對元件電荷收集效益的影響。
本研究所製作元件之最佳條件（ITO/PEDOT:PSS/P3HT：F8T2：PCBM/Ca/Al）為主動層比例為P3HT：F8T2：PCBM＝0.4：0.6：2.75、快乾溫度為140℃、退火處理為110℃，其最佳元件轉換效率可達到0.95%。

In here, we studies effects of multiple-junction on the performance of polymer solar cells with blends of two donors, poly[9,9’- dioctyl-fluorene-co-bithiophene] (F8T2) and Poly(3-hexylthiophene (P3HT), and an acceptor, [6,6]-phenyl-C61-butyric acid methyl ester (PC[60]BM). Such multiple-junction devices comprising active materials with cascade energy level are expected to have efficient exciton dissociation and the higher open-circuit voltage (VOC). In comparison with the device with only P3HT/F8T2 blend the power conversion efficiency (PCE) of the multiple-junction devices was dramatically increase. Further reorganization of the film morphologies by optimizing fabrication conditions, the PCE of the photovoltaic devices increase from the roughly 0.35 to 0.95% under air mass 1.5 simulated solar illumination (100 mW/cm2).
