Facile synthesis of GO@SnO/TiO nanofibers and their behavior in photovoltaics.

Chemical doping is a widely-used strategy to improve the performance of TiO for the dye-sensitized solar cells (DSCs). However, the effect of two efficient dopants has been rarely investigated. We present the synthesis of GO@SnO/TiO nanofibers (NFs) by a facile method using electrospinning and hydrothermal processes.
