Abstract
Small-molecule organic photovoltaic (OPV) cell with a large open circuit voltage (VOC) has been achieved by introducing 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) as donor layer. In order to obtain large VOC of standard copper phthalocyanine (CuPc)/C60 OPV cell, a very thin layer of DCJTB was inserted between CuPc and C60. It was found that the device formed multicharge separation interfaces. The VOC of device with 2 nm DCJTB layer was increased from 0.44 to 0.58 V. Also, the atomic force microscope (AFM) 3D-images of the donor surfaces were characterize to discuss OPV cell performance improvement. Furthermore, the absorption spectrum shows that an additional thin DCJTB layer enhances the light harvest capability of the cell.
