Assessment of the Thickness of the Anti-Reflective Film of a Solar Cell by Color
摘要
Abstract
A method for estimating film thickness based on the color painting of the non-absorbing film-absorbing substrate system is proposed. The method can be useful for developing the technology of applying anti-reflective coatings to solar cells. The thickness of a dark blue anti-reflective SiO film applied to a silicon wafer was determined to illustrate the method.
