摘要	Authors demonstrated impact of series small ratio donors in C60 matrix on photovoltaic (PV) performance. A series of donor materials such as N,N-Di-1-naphthyl-N,N-diphenyl-1, 1-biphenyl-4,4-diamine (NPB), 4,-4-Bis(carbazol-9-yl) (CBP), 4,4,4-tris(N-3-methylphenyl-N-phenyl-amine)triphenyl-amine (m-MTDATA), copper phthalocyanine (CuPc) and 4,4,4-tris(n-carbazolyl-triphenyl- amine) (TCTA) were blended with fullerene (C60) by different ratio. It was found that although donor-acceptor (DA) interface in planar heterojunction (PHJ) structure increased charge separation probability at the near interface section, the PV response was stronger for bulk heterojunction (BHJ) with low-ratio donor doping into C60 matrix in which exciton dissociation can take place immediately after photon absorption without a diffusion progress. The power conversion efficiency (PCE) of BHJ-PV cell based on NPB donor reaches 2.25%, which is double of that of the PHJ cell. In terms of our series results we obtained that EHOMO (HOMO C60-HOMOdonor) between C60 acceptor and donors would provide a maximal influence on achievement of a maximal PCE and an optimal EHOMO locates around 0.8 eV, which implies that dissociation of photo-exciton at C60 matrix needs feasible driving force. More detail mechanism was also argued. 2013 Elsevier B.V. All rights reserved.
