| 英文摘要 | An organic photovoltaic (OPV) device based on a carbazole-derived copolymer poly[N-9'-heptadecany1-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1', 3 -benzothiadiazole)] (PCDTBT) and N,N'bis(1-ethylpropyl)-perylene-3,4,9,10-tetracarboxylic diimide (EP-PDI) was fabricated by incorporating alcohol-soluble phosphate group-containing perylene diimide derivative (PDIP) as a cathode interfacial layer. The final performance of PDI-based OPV device modified by PDIP layer enhanced due to both optimized interfacial contact and the formation of interfacial dipole. Firstly, the film roughness of active layer was reduced from 8.8 nm to less than 4.0 nm by the introduction of the relatively amorphous PDIP layer. Meanwhile, the surface of active layer became more hydrophilic with significantly decreasing the contact angle from 90 degrees to 78 degrees. Secondly, an interfacial dipole between active layer and metal electrode was formed as indicated by the surface potential measurement, which not only enhanced built-in potential but also improved charge transport and extraction. Thus, the final improved device performance of PDI-based OPV device with simultaneous enhancement of open-circuit voltage (V-oc) and short-circuit current density (J(sc)) was achieved.
