有機共軛高分子軟性基板太陽能電池具有製程簡易適用於捲軸式連續製程、可製作大面積、質輕易於攜帶且屬於可撓性元件應用層面廣泛等優點，也是非常具有發展潛力且為研究低成本太陽能電池的重要領域。
在本研究以P3HT(poly(3-hexylthiophene))與PCBM( [6,6]-phenyl-C61-butyric- acid methyl ester)共軛高分子當作主動層吸光材料，結構上則是以P3HT與PCBM混合於鄰二氯苯(1,2-Dichlorobenzene, DCB)中，塊材異質接面(bulk heterojunction)能夠有效的提高載子的傳輸效率，利用旋轉塗佈(spin-coating)的方式成膜在可撓曲式軟性基板上，選用已經圖案化氧化銦錫(Indium Tin Oxide, ITO)的polyimide (PI)基板和polyethylene terephthalate(PET)基板。
研究中成功製作出在PI基板上高能量轉換效率(power conversion efficiency, PCE)有機共軛高分子太陽能電池，PCE值已經達3.8%是目前世界最高效益，整體元件效益和之前最高紀錄相比提升達13%。PET基板上的有機共軛高分子太陽能電池利用微波針對電動傳輸層(PEDOT:PSS)加熱方式有顯著的效果，加熱特性具有選擇性、加熱快速和節能的優點。

Conjugated polymer solar cells on flexible substrate exhibit many advantages such as the simple processing feasibility for roll-to-roll continuously fabrication、potential to scale up and for large area、lightweight、easy to carry and the extensive application. Therefore, polymer solar cells are under intensive important research.
In this study, we use P3HT and PCBM conjugated polymer as absorption material. A better structure called bulk heterojunction by P3HT and PCBM blending system in DCB, and spin-coating on patterned ITO PI and PET flexible substrates.
We successfully developed the highest PCE 3.8% on PI substrate of the global research and promote the PCE 13% higher than that was done on the flexible substrate before. In PET substrate series, organic solar cells with microwave annealing show the PCE of 1.51% which is higher than that of the cells with hot plate annealing or non-treatment.
