Abstract

This thesis investigates the n-i-p planar hybrid perovskite solar cell of structure glass-ITO / compact TiO2-Cl / (FAPbI3)0.85(MAPbBr3)0.15 / spiro-OMeTAD / Au. The main focus is on the investigation of the TiO2-Cl nanocrystal electron transport layer. In particular, the influence on the solar cell performance of varying the type of dispersion solvent used, the thickness of the layer and dispersion concentration is investigated. It has been found that using hydrous MeOH instead of anhydrous MeOH as co-solvent for dispersing the nanocrystals decreases the average PCE by 4.32%. Then, by increasing the TiO2-Cl layer thickness from 22 nm to 44 nm increases the average PCE with 5.31%. Additionally, decreasing the TiO2-Cl dispersion concentration from 20 mg/mL to 15 mg/mL in Chloroform:MeOH solvents increases the average PCE by 0.74%.
