제목 A conjugated polyelectrolyte dipole layer induced at donor and acceptor interface in organic trilayer solar cells
초록 We report solution-processed organic trilayer solar cells consisting of P3HT, a CPE and PCBM, wherein the CPE exists as an interlayer within the donor-acceptor junction. The influence of interlayer thickness on device properties was investigated as well as the behavior of molecular dipoles in the trilayer solar cells when influenced by external electrical stimuli. We find that incorporation of an interlayer which is too thick results in decreased performance due to reduced JSC, VOC, and FF. However the VOC is found to increase slightly when a thin CPE layer is used in conjunction with an external electric field. These results provide an experimental approach for investigating the influence of interfacial dipoles on the on the solar cell parameters and behavior of charge separating organic donor/acceptor junctions, yielding fundamental information about the donor/acceptor interface in organic solar cells.
