AB  - Perovskite solar cells (PSCs) have attracted tremendous research attention due to 
      their potential as a next-generation photovoltaic cell. Transition metal oxides 
      in N-I-P structures have been widely used as electron-transporting materials but 
      the need for a high-temperature sintering step is incompatible with flexible 
      substrate materials and perovskite materials which cannot withstand elevated 
      temperatures. In this work, novel metal oxides prepared by sputtering deposition 
      were investigated as electron-transport layers in planar PSCs with the N-I-P 
      structure. The incorporation of tungsten in the oxide layer led to a power 
      conversion efficiency (PCE) increase from 8.23% to 16.05% due to the enhanced 
      electron transfer and reduced back-recombination. Scanning electron microscope 
      (SEM) images reveal that relatively large grain sizes in the perovskite phase 
      with small grain boundaries were formed when the perovskite was deposited on 
      tungsten-doped films. This study demonstrates that novel metal oxides can be used 
      as in perovskite devices as electron transfer layers to improve the efficiency.
