Abstract
In this paper, ZnO seed layer was prepared on glass substrate by sol-gel method, and ZnO nanorods were grown on the seed layer by hydrothermal method. ZnO fi lms with nanorod structures were obtained. B y changing the concentration of hydrothermal growth, diff erent ZnO fi lms with nanorod structures were obtained, and the structure, morphology, transmittance and light trapping properties of the fi lms were characterized. The optical properties of ZnO fi lms with nanorod structures under diff erent growth conditions were studied in order to improve the light trapping properties of ZnO fi lms while ensuring high transmittance of the fi lms.
