This article represents the spectral responses of a planar FTO/CdS or TiO 2 /C s2 TiI 6 - X Br X /CuSCN/Ag based structure where CdS and TiO 2 is used as Electron transport layer (ETL) and CuSCN as Hole transport layer (HTL) under 300 K temperature condition with the SCAPS-1D simulator. The simulation was performed at 750 nm thickness of C s2 TiI 6 - X Br X absorbing material where x = 0 to 6 to understand the quantum efficiency (QE) using two different ETL (CdS and TiO 2 ). This article shows that TiO 2 as ETL has better spectral responses from 300 nm to 900 nm wavelength compare to CdS.
