Effective conversion efficiency enhancement of solar cell using ZnO/PS antireflection coating layers

► ZnO deposited on PS layer using RF system while the PS prepared by a PECE method. ► ZnO/PS layers are excellent ARC layers, exhibiting exceptional light trapping. ► High 18.15% solar cell efficiency was obtained with ZnO/PS ARC layers. ► PL emission peaks proved the nanocrystalline characteristic for all the layers. ► Raman measurements indicate that a high-quality was obtained for all the layers.
