Abstract—The application of zinc oxide (ZnO) thin film as transparent conductive oxide (TCO) layer in thin film solar cells (TFSC) has high potential because of the various advantages of ZnO over other TCO materials. In this paper, the influence of the crater-like texture of ZnO layer on the optical properties and performance of the solar cell is investigated. Using the commercial simulation software RSoft Fullwave and RSoft Solar Cell Utility, we designed solar cells with crater-like textured ZnO layers as TCO and varied the crater depth along with overall ZnO thickness. It was found that, the crater-like textured ZnO layer provides better light trapping with increased crater depth as well as higher conversion efficiency near the IR region in the solar spectrum.
