摘要: | The fabrication of silicon oxynitride (SiON)/ZnO nanotube (NT) arrays and their application in improving the energy conversion efficiency (eta) 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 similar to 2.0 (Si3N4 and ZnO) to 1.72 similar to 1.75 (SiON) to 1 (air). Experimental results show that the use of 0.4 mu m long ZnO NT arrays coated with a 150 nm thick SiON film increases Delta eta/eta by 39.2% under AM 1.5 G (100mW/cm(2)) illumination as compared to that of regular SCs with a Si3N4/micropyramid surface. This enhancement can be attributed to SiON/ZnO NT arrays effectively releasing surface reflection and minimizing Fresnel loss. |
