Mesoporous SnO2nanoparticle films as electron-transporting material in perovskite solar cells

摘要：

　　Perovskite solar cells with mesoporous metal oxide films as scaffold layers have been demonstrated very impressive advances in performance recently.Here, we present an investigation into mesoporous perovskite solar cells incorporating mesoporous SnO2nanoparticle films as electron-transporting materials and scaffold layers, to replace the traditional mesoporous TiO2 films.By optimizing the SnO2 film thickness and treating the surface of SnO2 film with TiCl4aqueous solution.Due to the TiCl4 treatment significantly retards the recombination process, the short-circuit current density (Jsc) and open-circuit voltage (Voc)reached to nearly 18 mA cm-2 and 1 V, respectively.Consequently, the power conversion efficiency of device with SnO2 film exceeding 10%.
