Abstract
In this work, we report polymer solar cells based on blade-coated P3HT:PC71BM and PBDTTT-EFT:PC71BM bulk heterojunction photoactive layers. Enhanced power conversion efficiency of 2.75 (conventional structure) and 3.03% (inverted structure) with improved reproducibility was obtained from blade-coated P3HT:PC71BM solar cells, compared to spin-coated ones. Furthermore, by demonstrating 3.10% efficiency flexible solar cells using blade-coated PBDTTTEFT:PC71BM films on the plastic substrates, we suggest the potential applicability of blade coating technique to the highthroughput roll-to-roll fabrication systems.

본 연구에서는 대면적 용액 인쇄장비인 닥터블레이드 코터를 이용하여 형성된 P3HT:PC71BM 및 PBDTTTEFT:PC71BM 벌크헤테로 졍션을 기반으로 하는 고분자 태양전지를 보고한다. 블레이드 코팅 인쇄공정으로 제작된 정구조와 역구조의 P3HT:PC71BM 고분자 태양전지로부터 기존 스핀코팅법으로 제작된 태양전지 성능보다 우수한 2.75, 3.03%의 광전변환효율을 얻을 수 있었을 뿐만 아니라, 개선된 소자 성능의 균일도가 확보됨을 확인하였다. 나아가 블레이드 코팅 공정을 이용하여 3.10%의 광전변환효율을 나타내는 PBDTTT-EFT:PC71BM 기반의 플렉시블고분자 태양전지를 구현함으로써 블레이드 코팅법이 향후 대면적 고속 롤투롤 프린팅 인쇄공정에 효과적으로 활용될 수 있음을 제시하였다.
