Abstract

See full text

Provided are methods for forming antireflective layers on solar cells using wet chemical processes and solar cells with anti-reflective layers formed of ZnO based nanorods. Self-assembling ZnO nanorods are generated in the chemical solution without any catalysts. The nanorods are formed to different shapes such as hexagonal, cubic, and circular in cross-section. The refractive index of the ARC layer formed of the nanorods is modulated by controlling the diameter and length of the nanorods by controlling the Molarity of the solution used to form the nanorods. A correlation is established between the refractive index and solution Molarity and a solution is prepared with the desired Molarity. The nanorods are formed from HMT ([CH2]6NH4) and a dissociative Zn2+/OH chemical such as Zn(NO3)2.
