摘要

有機共軛高分子太陽能電池因為材料具有許多良好的特性，在製程上相當容易製作，且具備了可撓曲性，能夠應用於更廣大的設計需求，而利用刮刀成膜或噴墨印刷等方式，使元件能朝向大面積、大尺寸的方向發展，未來前途不可限量。
單層有機高分子太陽能電池的效率已達瓶頸，要向下發展勢必要朝多層結構邁進，而互溶問題為製作多層結構時所需克服的困難之一，本論文利用丙二醇材料當作緩衝層，能夠有效解決不同層之間的互溶問題，成功製作出全溶液製程的多層元件，同時我們也證明了多層結構對於元件特性的提升大有幫助。

Polymer solar cells (PSCs) exhibit many advantages such as simple processing, flexibility and the potential to scale up to large area by using blade coating or ink-jet printing techniques. Interlayer mixing is one of the main problems for achieving PSCs with multilayer structure. In this study, we solved the problem by a buffer layer technique. The result showed that the technique which employs glycol as a buffer layer successfully circumvented the interlayer mixing and made the multi-layer devices achieveable with all-solution process. We also demonstrated that the device performance was greatly enhanced with a multi-layer structure.
