제목 Synthesis and characterization of PFN with different backbone structures for polymer solar cells
초록 We synthesizd a PFN series based on (9,9-bis(3’-(N,N-dimethylamino)propyl)-2,7-fluorene) as an cathode buffer layer (CBL) in the inverted device for orgnaic solar cells. The three kind of back bond compromise PFN conjugated polymer were named Poly[(9,9-bis(3’-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-4,7-thiophene) (PFN-T), Poly[(9,9-bis(3’-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt4,7-(2,1,3-benzothiadiazole)]) (PFN -BT), and Poly- [(9,9-bis(3’-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt4,7-dithienyl-2,1,3 benzothiadiazole) (PFN -TBT). The contact between the donor and the n-type interlayer make an extra interface, which provide charge dissociation. Interface gives efficient electron extraction form the bulk heterojunction, which finally obtains much improved device performance. The highest device performance of PFN-BT accomplished 9.94% and Conjugated polymer onto the ZnO surface achieved high device performance of 9.9 (with a fill facetor more than 60%).
