| Research Abstract |
Since the nanoscopic domain structure in bulk heterojunction organic thin film solar cell is formed randomly, the photoinduced carriers are concerned to be deactivated before collected by the electrodes. In this study, we have investigated the photovoltaic properties of an organic thin film, in which nanofibers of conductive polymer were packed with acceptor materials. By using the electrospinning method, the densely-packed P3HT nanofibers with a diameter of several hundred nanometers were fabricated. After that, the nanofibers were packed with PCBM by a solution process, and an intended organic nanoscale heterostructure with a conduction path for the photoinduced carriers was fabricated. We evaluated the electric properties of this sample, and observed the short-circuit current density of 0.12 mA/cm2.
