AB  - The implementation of positive alternative electron transporting layers (ETLs) 
      with excellent electronic properties is a most promising method to up-scale 
      low-cost highly efficient perovskite solar cell (PSC) technology. The present 
      work demonstrates the preparation of tin oxide (SnO2) nanofibers (NF) and 
      nanobelts (NB) as an electron transporting layer (ETL) for PSCs. The smooth and 
      uniform nanofibers and nanobelts have been prepared using an electrospinning 
      technique followed by calcination at 600  degrees C. Thermogravimetric analysis (TGA) 
      analysis performed on the as-spun polyvinylpyrrolidone-tin oxide (PVP-SnO2) 
      composite suggests that a calcination temperature of 600  degrees C is required to obtain 
      pure SnO2 and to ensure complete removal of PVP along with other organic 
      solvents. The structural analysis confirmed the presence of the pure tetragonal 
      rutile phase of SnO2 nanofibers and nanobelts. The prepared nanofibers and 
      nanobelts were further used as ETLs for PSCs. Our optimized experimental 
      parameters yielded a JSC of 22.46 mA cm-2, a VOC of 1.081 V and FF of 66%, 
      leading to >16% power conversion efficiency (PCE) for SnO2 nanobelts using an 
      (FAPbI3)0.85(MAPbI3)0.15 perovskite absorber layer with good stability. The 
      obtained PCE is much higher than that of the SnO2 NF (12.893%) morphology. 
      Nevertheless, the synthesis of SnO2 NF/NB ETLs provides a simple, low-cost and 
      large-scale method for PSCs.
