Abstract

Optical characteristics in polymer films of MEH-PPV/DFPP blends were for the first time investigated. DFPP (N, N'-diperfluorophenyl-3,4,9,10-perylenetetracarboxylic diimide) used here was a novel n-type polymer, which had good stability in air and solubility in common solvents. For a 1:9 DFPP:MEH-PPV blend, highly efficient quenching of photoluminescence (PL) was observed. In addition, the photocurrent responses of these MEH-PPV/DFPP photovoltaic cells were measured. When the light intensity was $50mW/cm^2$, short-circuit photocurrent densities were two times higher than those of single layer MEH-PPV devices.

MEH-PPV/DFPP 혼합물의 고분자 박막에서 광학적 특성들이 최초로 조사되었다. 여기서 사용된 BFPP(N, N'-diperfluorophenyl-3,4,9,10-perylenetetracarboxylic diimide)는 새로운 n형 고분자인데 공기 중에서 안정성이 우수하고 일반 용매에서 잘 용해되었다. 1:19 DFPP:MEH-PPV 혼합물의 경우 매우 효율적인 형광소멸이 관측되었다. 더불어 이 MEH-PPV/DFPP 광전 셀의 광전류 응답특성들이 측정되었다. 빛의 세기가 $50mW/cm^2$일 때 단락전류 밀도는 단일 층의 MEH-PPV 소자들보다 2배 이상 되었다.
