Abstract

The fabrication of silicon oxynitride (SiON)/ZnO nanotube (NT) arrays and their application in improving the energy conversion efficiency (η) of crystalline Si-based solar cells (SCs) are reported. The SiON/ZnO NT arrays have a graded-refractive-index that varies from 3.5 (Si) to 1.9 2.0 (Siand ZnO) to 1.72 1.75 (SiON) to 1 (air). Experimental results show that the use of 0.4 m long ZnO NT arrays coated with a 150 nm thick SiON film increases Δ η / η by 39.2% under AM 1.5 G (100 mW/cm 2 ) illumination as compared to that of regular SCs with a Simicropyramid surface. This enhancement can be attributed to SiON/ZnO NT arrays effectively releasing surface reflection and minimizing Fresnel loss.
