摘要

A thermally oxidized, Ni/Au transparent electrode was applied on a glass substrate to fabricate CH 3 NH 3 PbI 3 perovskite/C 60 PHJ hybrid solar cells. The combination of oxidized Ni(NiO x ) with an interconnected Au network formed a functionalized Au:NiO x electrode, capable of transporting holes and blocking electrons from the CH 3 NH 3 PbI 3 perovskite to reach the electrode. Changing the Ni/Au compositions and the annealing conditions varied the optical transparency, electric conductivity, the work function of the Au:NiO x electrode, as well as the photovoltaic shows the energy-level diagram of each layer. The Au:NiO x film was prepared by sequential deposition of thin layers of Ni and Au on the glass substrate in an electron beam evaporator. After this step, the bilayer Ni/Au was thermally oxidized in O 2 atmosphere for 5 minutes at different annealing temperatures. Through the interdiffusion process of the Ni/Au bilayer, Au formed an interconnected metallic network structure as the transparent electrode. Ni diffused to the bilayer surface and oxidized into NiO x thus forming an appropriate electrode interlayer with the CH 3 NH 3 PbI 3 perovskite.
