국문 초록 (Abstract)

본 연구에서는, F4-ZnPc 광활성층 기반의 저분자 유기태양전지의 성능을 최적화 하기 위해서 다 양한 조건의 홀이동층과 전자이동층을 조합하는 연구를 진행하였다. BF-DPB 호스트 유기물에 C60F36 또 는 NDP9 도펀트를 도핑한 조합을 홀이동층으로 사용하였고, 전자이동층으로는 W2(hpp)4가 도핑된 C60 또는 순수 C60/Bphen 물질을 사용하였다. 다양한 홀/전자이동층의 조합은 유기태양전지의 단락전류밀도와 fill factor, 효율에 영향을 끼치는 것을 관찰할 수 있었다.

다국어 초록 (Multilingual Abstract)

We optimize the performance of small-molecule organic solar cells based on the F4-ZnPc active layer with a combination of hole and electron transport layers. Either C60F36 or NDP doped BF-DPB layers are applied as the hole transport layers and either W2(hpp)4 doped C60 or pure c60/Bphen layers are uaed as the electron transport layers for organi solar cells investigated here. It is observed that various combination of hole and electron transport layers affects on the photovoltaic performance of organic solar cells in terms of short circuit current densities, fill factors, and power conversion efficiencies of devices.
