利用微奈米轉印技術製作高次序體異質接面結構有機太陽能電池

Abstract

本論文以簡單之微奈米轉印技術製作出高次序有序結構的體異質接面有機太陽能電池，並討論製程中許多的參數條件對有機太陽能電池的影響。 在製作高次序有序結構的有機太陽能電池主動層部分，先利用微奈米成形技術製備一母模，利用矽膠高分子材料翻模得一轉印章，在轉印章上以塗佈方式塗佈上一層有機薄膜後，直接以簡單之轉印方式，將具有特定圖形結構的薄膜轉印至另一目標基板上；並使用正交溶液之特性，可以避免在塗佈第二層有機材料時，將已經轉印之具有圖形結構的有機薄膜發生互溶的效應。所以本論文之具有結構之有機太陽能電池以全溶液製程方式製作，具有製程簡單快速、可大面積化、具可撓性等優點。

This thesis is about using micro-transfer printing technology to produce organic solar cells of highly-ordered bulk hetero-junction structure, and reviewing the effects of various processes parameters on the cell. In the making of the cells active layer of the bulk hetero-junction(BHJ) structure, micro and nanopatterning techniques were used to produce the mold. Polymer material molding(PDMS) were adopted for transfer stamping. After spin coating a layer of organic thin film on the transfer stamp, we used simple transfer printing techniques to transfer the structure of the thin film to another plate. The use of orthogonal-solvant is also vital when the second layer of organic materials is to be coated inorder to prevent dissolving the first layer organic thin film on the plate. With all these processed taken, into consinderation, process introduced in the making of structured organic solar cells are therefore simple, swift, flexible, and most importantly, can be produced in large areas.
