Abstract
따라서 은나노와이어를 포함하는 잉크를 이용하여 플렉시블 지지체 상에 은나노와이어를 전사하므로, 원하는 형상으로 투명전극을 제조할 수 있으며, 선형 또는 면형의 일정한 형상을 가지는 패턴이 형성된 투명전극을 제조할 수 있다. 다양한 형상의 투명전극은 유연전자 소자 및 태양전지에 응용될 수 있으며, 은나노와이어를 직접 도포하는 과정을 대체하여 고가의 은나노와이어의 사용량을 감소시킬 수 있다.
Description
도 2는 본 발명의 실시예에 따른 패턴이 형성된 투명전극 제조방법의 공정 흐름도이다.
도 3은 본 발명의 실시예에 따른 패턴이 형성된 투명전극 제조방법의 기능층을 제조하는 단계를 나타낸 공정흐름도이다.
도 4는 본 발명의 실시예에 따른 패턴이 형성된 투명전극의 전자현미경(scanning electron microscopy; SEM) 사진이다.
