摘要：

Understanding the inversely correlated series resistance (R-s) and parallel resistance (R-p) remains a challenge. Here ve report that the variation of R-s and R-p is inversely related through the morphology of the donor and acceptor interface in CuPc organic solar cells, when comparing the bilayer structure and bulk heterojunction structure. It was also found that the charge carrier concentration near the donor acceptor interface plays an important role in the relationships of R-s and R-p under fixed interfacial morphology, which was verified by the change of V-oc. The inversely correlated R-s and R-p contributes to the improvetnent of the fill factor, and in turn the power conversion efficiency. (C) 2015 Chinese Materials Research Society.
