We present an efficient tandem polymer organic solar cell (OSC), consisting of the P3HT:PCBM blend as the active layer, in which the bottom and top cells are connected optically and electrically by an Al and MoO3 intermediate layer. Such an intermediate layer has high transparency and can implement the connection of the bottom and top cells in series. The main absorption range of the active layer...
The refractive indices of textured indium tin oxide (ITO) and zinc oxide (ZnO) thin films were measured and compared. The ITO thin film grown on glass and ZnO buffered glass substrates by sputtering showed distinct differences; the refractive index of ITO on glass was about 0.05 higher than that of ITO on ZnO buffered glass in the whole visible spectrum. The ZnO thin film grown on glass and ITO buffered...
In this paper, we report a buffering method of improving the quality of ITO thin films on glass by r.f. magnetron sputtering. By applying a ZnO buffer before the ITO deposition in the same run of sputtering, ITO films showed single (111)-oriented highly textured structure, while ITO films showed mixed-oriented polycrystalline structure on bare glass. A design of experiment was taken out to minimize...
