AB  - In spite of the impressive progresses regarding perovskite-type solar cells, a 
      clear understanding about underlying mechanisms therein is still sparse, 
      especially because of the absence of spatially resolved device characteristics 
      which should be linked to exciton formation efficiency, morphology, and 
      crystallinity being estimated as functions of positions within active layers. 
      Here, the planar CH(3)NH(3)PbI(3) (MAPbI(3)) perovskite solar cells (PeSCs) with 
      ZnO as the electron-transporting layer (ETL) were fabricated. By varying the wide 
      range of MAPbI(3) active-layer thickness, we estimate their device parameters and 
      external quantum efficiencies in addition to internal absorption spectra (Q) by 
      means of the transfer matrix method. Furthermore, the spectrally and spatially 
      resolved internal quantum efficiencies (IQEs) as a function of the active-layer 
      thickness within PeSCs were calculated, and the relationship between IQE and 
      device parameters extracted from the current-voltage ( J- V) behaviors was 
      discussed. It was found that the PeSC with MAPbI(3) film thickness around 303 nm 
      has a relatively high IQE and PCE, indicating that there is more power loss of 
      PeSCs when the thickness of the MAPbI(3) layer is either less or more than about 
      300 nm. Furthermore, time-resolved photoluminescence together with the 
      thickness-dependent morphology and crystallinity of the MAPbI(3) film demonstrate 
      that there are two power loss processes in the fabricated PeSCs: one at the 
      ZnO/MAPbI(3) interface and the other in bulk. The present research is beneficial 
      for further understanding of the fundamental physics for the PeSCs based on the 
      ZnO ETL.
