本論文研究使用兩種高效率有機太陽能電池材料，分別為PBDTTT-EFT Poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b']dithiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2-carboxylate-2-6-diyl)] 與 PTB7 Poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]]，使用刮刀塗佈製程，達到高度材料使用效率，並可應用於未來大面積化發展。
第一部分為在PBDTTT-EFT有機太陽能電池上進行熱退火、加速退火、蒸鍍機腔體退火，觀察其經快速退火後初始效率改變與壽命持續操作表現，目前經3190小時後，PCE仍維持6.04%，為目前持續操作有機太陽電池最佳壽命。
第二部分為在PTB7有機太陽能電池上進行熱退火、加速退火、改變蒸鍍電極，觀察其經熱處理後初始效率改變與後續壽命持續操作之表現，經過使用蒸鍍電極LiF熱退火975小時後，其PCE仍維持5.58%。

This thesis uses two high efficiency organic solar materials, which are Poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5- b']dithiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2- carboxylate-2-6-diyl)] (PBDTTT-EFT) and Poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5- b']dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4- b]thiophenediyl]] (PTB7). Blade coating is used for the deposition of the active layer as it can achieve high material usage and is scalable to large area OSC in the future.
The first part is the treatment on PBDTTT-EFT OSC by thermal annealing, rapid thermal annealing (RTA) and thermal annealing during deposition. We record the initial PCE and observe the lifetime with continuous operation on the device. With RTA, PBDTTT-EFT OSC remains a PCE of 6.04% after 3190 hours, which is the best performance in the continuous operation of OSC.
The second part is the treatment on PTB7 OSC by thermal annealing, RTA and changing deposition metal. We record the initial PCE and observe the lifetime with continuous operation on the device. With thermal annealing, PTB7 OSC remains a PCE of 5.58% after 975 hours.











Keywords: organic solar cells, PBDTTT-EFT, PTB7, thermal treatment, blade coating, lifetime
