Abstract
The experimental results of a perovskite solar cell with FTO/TiO2/CH3NH3PbI3/PEDOT:PSS/Pt cell architecture fabricated in our research laboratory under ambient conditions are compared with the simulated results obtained using SCAPS-1D. Optimization of the thickness of the perovskite, ETL and HTL, temperature, and the work function of the metal has been carried out to formulate a high-performance perovskite solar cell. The impacts of varying absorber thickness, ETL, temperature, and metal work function exhibit very minimal or no change. However, the device exhibits a high power conversion efficiency (PCE) in HTL thickness variation. The impact of variation in HTL thickness from 10 nm to 500 nm shows the best cell performance in terms of PCE between 10 nm and 50 nm. At 10-nm thickness, Jsc, Voc, FF, and PCE are 35.08 mA/cm2, 0.95 V, 35.08%, and 28.93%, respectively. The cell efficiency decreases with the increase in the thickness of HTL. However, at lower thicknesses, the extraction of the generated carrier is generally low. Therefore, analyzing all the results, we suggest that, to obtain a high power conversion (26.26% at 30 nm and 23.75% at 50 nm), the HTL thickness should effectively be between 30 nm and 50 nm. The structure of the studied solar cell device having such cell characteristics can be considered in the manufacturing workflow for its mass-scale production.
