摘要

本實驗室致力於軟性電子製程開發，其重點在於大面積塗佈於軟性基板上，而關鍵點在於如何低溫、均勻性與高速度之下塗佈有機高分子薄膜，以未來量產應用之捲對捲印刷製程為目標，而本實驗室開發之自調式刮刀塗佈之技術PMMA膜厚已可達到一、兩百奈米並且PMMA薄膜可達到10%平整度。
　　但此技術只以介電高分子PMMA驗證過，為了瞭解本創新自調式刮刀塗佈技術的多樣性，本文將針對P3HT進行刮刀塗佈的研究做一系列的探討；並對刮刀塗佈P3HT的初步實驗所產生的問題做改善，如基板寬度的定義以及塗佈高分子薄膜不均勻等問題，以實作了解其發生的原因並建立薄膜厚度與控制因子參數相關數據，最後利用此製程技術於不同有機高分子材料上，並應用於大面積有機太陽能電池之製作，包括電動傳輸層PEDOT:PSS以及光伏材料P3HT/PCBM之薄膜塗佈。

Our group have devoted to flexible electronics fabrication for a long time. It focuses on the large-area coating of the flexible substrate. How to coat organic polymer film at low temperature, uniformity and high speed will be the important key points of production and application roll to roll printing processes. Our laboratory have developed self-adjusting blade coating technology PMMA, the thin film thickness can be achieved one or two hundred nanometers and the films can achieve 10% flatness.
　　However, this technology is only satisfied on the dielectric polymer PMMA. In order to understand the diversity of innovative self-adjusting blade coating technology.　　Therefore, this paper will focus on P3HT by blade coating. And improve the problems of blade coating P3HT in the preliminary experiment, such as the definition of the substrate width and uneven coating polymer film. By experiments, we can understand the reasons for its occurrences and implement to establishment the film of thickness and the control factor parameter data. Finally, using this process technology in different organic polymer materials and in the production of large area organic solar cells, including electric transport layer of PEDOT:PSS and photovoltaic materials P3HT/PCBM the film coating.
