Abstract

The paper presents the investigation on the anti-reflection property of 2-dimensional periodic structures on silicon surface for high efficiency solar cells. The characteristics of micron-to-submicron periodic surface-relief structures for broadband anti-reflection silicon layers are studied theoretically and experimentally. Theoretical analysis is carried out to determine the appropriate sturcture period. Hexagonal and cross grating structures were fabricated on the surfaces of silicon wafers using hologrpahic and wet etching techniques. Measurement on the silicon wafers with fabricated structures shows significant reduction of surface reflection for the wavelength from 300 nm to 1100 nm.
