본 발명은 유기 박막 트랜지스터 제조에 사용되는 유기 반도체 박막 제조 방법에 관한 것으로서, 보다 상세하게는 유기 반도체와 절연성 고분자를 혼합하여 제조되는 유기반도체/절연성 고분자 블렌드 박막과 이를 이용하여 제조되는 유기 박막 트랜지스터에 관한 것이다. 본 발명에 있어서, 유기 반도체 박막은 유기 반도체 나노 섬유가 절연성 고분자 층 내에 네크워크 형태로 분산되어 있다. 이러한 유기 반도체 박막은 유기 반도체/절연성 고분자 블렌드를 유기반도체의 한계성 용매에 용해시켜, 용해도를 조절하여 코팅함으로써 형성될 수 있다. 본 발명에 따른 유기반도체/절연성 고분자 블렌드 박막은 3중량% 정도의 유기 반도체를 포함하면서도 유기 반도체만 사용한 박막과 동일한 수준의 전기적 특성을 나타낸다. 더불어 절연성 고분자를 유기 박막 트랜지스터의 보호층으로 사용할 수 있기 때문에 보호층 형성 공정을 줄일수 있다. 유기 박막 트랜지스터, 유기반도체, 블렌드, 한계성 용매, 유기반도체 나노 섬유

PURPOSE: An organic solar cell and a manufacturing method thereof are provided to improve light conversion efficiency by increasing a light absorption rate and degree of crystallization of the light active layer. CONSTITUTION: A first precursor solution, which is made by melting a first light active material and a second light active material at a first solvent, is prepared. A second solvent is added to the first precursor solution and a second precursor solution is prepared. A light active layer(40) is formed by spreading the second precursor solution on a substrate(10) in which a first electrode(20) is formed. An assistant layer(30), which protects the first electrode between the first electrode and the light active layer, is formed. A second electrode(50) is formed on the light active layer.
