Reduced graphene oxide (RGO)/titanium oxide (TiOx) (RGO/TiOx) composite films are successfully prepared by a sol-gel method. Inverted organic solar cells incorporating RGO/TiOx composite as electron transport layer and MoO3 as hole transport layer were fabricated. A short-circuit current of 9.85mA/cm2 and power conversion efficiency of 3.82% are achieved by using the RGO/TiOx composite films with...
The pristine TiO x and Zn-doped TiO x films with the different Zn/Ti doping ratios were prepared by a sol-gel method on ITO substrates, and used as electron transfer layers in inverted organic solar cells based on P3HT:PCBM. The highest electron mobility was achieved in the film with a Zn/Ti atomic ratio of 0.8%. The photovoltaic device based on the 0.8% Zn-doped TiO x film...
