유기 태양전지 제작이 가능한 와이어리스 바코터 개발

Studies are using a roll forming bar. A bar coating device available for a variety of coating conditions was developed. It is characterized by the bar forward and reverse rotation, fine-tune coating speed, and stripe coating. To determine the characteristics of the equipment, the coating tests under different coating conditions were carried out. As a result of the coating tests, the equipment was confirmed as one of strong candidates for the production tool of organic solar cells. The further production test of organic solar cells through stripe coating is in progress.
