Glass texturing is an effective method for changing the surface morphology to improve light trapping. In this paper, the technique is applied to hybrid inorganic-organic solar cells (perovskite solar cell) to enhance light trapping and current density. We optimized wet chemical etched fluorine doped tin oxide (FTO) coated glass substrates using a simple treatment then compared the mesoscopic and planar structures. Thus, we present the implication study of the wet etching process with a random pattern surface that enables punch light scattering and ideally balanced the optical and electrical properties of the perovskite solar cell. As a result, we achieved short-circuit current density for 26.5 mA/cm2 and PCE for 15.2 %.
