摘要：
Photoresponsive organic field-effect transistors (PhotOFETs) based on palladium phthalocyanine (PdPc) and C60 were fabricated with different donor-acceptor layer sequences. Both planar heterojunction devices fabricated exhibit better performance under illumination than the single PdPc device. PhotOFETs with the structure SiO2/C60/PdPc/Au exhibit a higher photosensitivity and photoresponsivity than that with the structure SiO2/PdPc/C60/Au. The origin for this is largely the high mobility of C60 and the well-matched LUMO levels of PdPc and C60. The maximum photosensitivity of the SiO2/C60/PdPc/Au device is 8 x 10(3), and the photoresponsivity is approximately 28 times that of the single component PdPc device.
