Abstract
Bismuth ferrite (BFO) is very promising as ferroelectric material for perovskite solar cell application. This study deals with the influence of thickness on optical properties of BFO layers grown on the quartz substrates by chemical solution deposition. XRD analyses revealed that all BFO samples have a dominant peak at (110) with rhombohedral perovskite structure. The optical bandgaps remained about 2.61 eV as the increasing of the thickness. However, the diffraction angle did not shift with increasing of the thickness. It can be concluded that structural distortion at both Fe sites and Bi sites in BFO layers does not occur
