Bare silicon has a high surface reflection of over 30%. The reflection is reduced by texturing and by applying anti-reflection coatings (ARC) to the surface 1. Anti-reflection coatings on solar cells are similar to those used on other optical equipment such as camera lenses.
The dielectric material and its thickness as an effective anti-reflection coating is decided by targeted wavelength range, where we want to minimize reflection. For c-Si solar cells, the wavelengths of our interest are 300–1200 nm, where we would need broadband anti-reflection effect for this whole wavelength range.
The graph shows the effect of a single layer anti-reflection coating on silicon. Use the sliders to adjust the refractive index and thickness of the layer.
