초록
본 연구에서 광경화성 아크릴 단량체 조성물(methyl methacrylate, 2-hydroxyethyl acrylate, poly(ethylene glycol) diacrylate)을 이용한 고분자 기판 내부에 실버그리드(silver grid)를 잉크젯공정(ink-jet)과 전사공정(transfer process)으로 함몰시킨 유연 투명전극 기판을 제조하였다. 인터페로미터를 사용하여 광경화된 고분자 기판 내부에 실 버그리드의 함몰된 형태 및 표면을 확인하였으며, 그것의 광학적 특성과 밴딩테스트 후 전기적 특성으로 제조된 유연 투명전극 기판의 물성을 고찰하였다. 유연 투명전극 기판으로서의 유용성을 확인하기 위해 poly(3-hexylthiophene): P3HT:[6,6]-phenyl-C61-butyric acid methyl ester(P3HT:PCBM)으로 유기 태양전지 소자를 제작하여 2.52%의 효율 특성을 얻었다.
Using the UV-curable acrylate formulations consisting of methyl methacrylate, 2-hydroxyethyl acrylate and poly(ethylene glycol) diacrylate), flexible and transparent electrode embedded silver grid into the polymer substrate was fabricated through ink-jetting technique and transfer process. The profile morphologies and surface characteristics of silver grid in the polymer substrate were estimated by interferometer. Furthermore, the optical properties as well as electrical- resistance changes during bending test of the electrode were also measured. As one of utilitarian applications for the electrode, the optimized organic solar cell was constructed on the electrode by using poly(3-hexylthiophene):[6,6]- phenyl-C61-butyric acid methyl ester (P3HT:PCBM) system and then power conversion efficiency of the device was 2.53%.
