在有機太陽能電池未來商業化與發展的趨勢下，除了轉換效率的提升外，在量產與成本以及元件的穩定性上更不容被忽視，本論文使用了刮刀塗佈製程除了能與roll-to-roll 的製程結合外，也加以應用於有效面積216cm2的元件上而此特點在於不須將多個太陽能電池模組化，而是在一次製程中即完成大面積化，因而大大降低時間與成本。
本論文除了上述太陽能電池的大面積化以外也成功地將溶液製程應用於界面層上，在ITO/PEDOT:PSS/PBDTTT-EFT:PC71BM/Liq/Al/Ag結構下達到4.76%的高轉換效率，而穩定性方面透過引入適當的界面層材料Liq與ZrOx，使元件壽命上獲得了大幅度的提升，在經過放置一個月持續80℃的高溫環境下分別維持了初始效率的65.8%與68%，而相較之下傳統熱蒸鍍LiF界面層在經過三天加熱下已衰退到初始效率的一半。
最後嘗試以ZrOx為主體下摻雜Liq，目的在於希望藉由摻雜材料之特性提升原材料初始效率，而在Liq為ZrOx莫耳濃度3%條件下開路電壓由11.45(V)提升至12.2(V)，FF由0.41至0.45而PCE由3.6%至4.17%，在穩定性上也獲的了良好的結果，在經過一個月持續80℃的高溫環境下維持了初始效率的70%。

In the future commercialization and development of organic solar cells, in addition to the improvement of power conversion efficiency, it is more important in terms of mass production and cost and stability. This thesis uses blade-coating process that not only can be combined with roll-to-roll process,but also applied on the device with active area of 216 cm2 and this feature is not necessary modularize a plurality of OSCs but complete the large-area OSCs in one process,therefore, the time and cost are greatly reduced.
In addition to the large area of solar cells, this thesi successfully applied the solution- processed interlayer, achieving a high power conversion efficiency of 4.76% under the device structure ITO/PEDOT:PSS/PBDTTT-EFT:PC71BM/Liq/Al/Ag . In addition, the stability of the device has been greatly improved through the use of suitable interlayers Liq and ZrOx, and remained 65.8% and 68% of the initial PCE at a high temperature of 80°C for one month. In contrast, the traditionally thermal evaporated LiF interlayer has already declined to half of the initial PCE after three days at 80°C high temperature.
Finally, we tried ZrOx doped by Liq. This purpose was to increase the initial PCE by the characteristics of the doped material, and the Voc was raised from 11.45 (V) to 12.2 (V) when the Liq was 3% of the ZrOx molar concentration, FF from 0.41 to 0.45 and PCE from 3.6% to 4.17%. Good results are also obtained in terms of stability, and 70% of the initial PCE is remained at a high temperature of 80°C for one month.
