Low Cost Anti-Reflection Coating for Photovoltaic Application

Abstract

Optical losses or the effect of reflection from surface of light-matter devices have a significantly influence on their accuracy, reliability and efficiency. Solar cells, including silicon substrate solar cells or dye sensitized solar cells, are one of them. The simplest way to improve the efficiency of solar cells is introducing an anti-reflection coating. This paper investigates the performance of anti-reflection coating by introducing a composite material, using different deposition methods. It is found that the annealing temperature of single anti-reflection layer can reduce to 600 °C by using our recipe. Moreover, the efficiency of three layer anti-reflection coating is modeled by MATLAB to demonstrate the gradient refractive index theory.
