Abstract

Perovskite CsPbBr3 has a band gap energy of 2.3 eV which has the potential for solar cell applications. The issue regarding the relationship between the different coating methods and the concentration has not been studied further. Therefore, this study focuses on analyzing the effect of variations in the concentration of CsPbBr3 20 mM and 40 mM as well as different coating methods, spin-coating, dip-coating and drop-casting on the morphology of the thin film. The ligand assisted reprecipitation LARP method was used to synthesize CsPbBr3 using control ligands, octylamine and oleic acid to obtain CsPbBr3 orthorhombic. Scanning Electron Microscopy (SEM) observations show that increasing the concentration resulted in larger particle size, and the Drop Casting method resulted in a more fully coverage on thin film. Drop Casting and a 40 mM solution produced the highest solar cell efficiency of 1.4 %.
