Get PriceIn order to determine the optimal refractive index, we developed a method which encompasses a combined analysis of the electrical and optical properties of SiN layers deposited on multicrystalline silicon solar cells.
The refractive index of optical materials should ideally be constant over the desired wavelength range and this is mostly the case for these materials, although ZnO and TiO2 show an increase in refractive index towards 400 nm.
The ideal refractive index, ni, for such a coating is given by equation (1): (1) n i = n 1 n 2 where n 1 and n 2 are the refractive indices of the existing layers. The refractive indices of air and glass are 1 and 1.5 respectively, so the ideal refractive index for a single layer AR coating between glass and air is 1.22.
However, no solid material has a refractive index this low. Magnesium fluoride (MgF2) is the closest viable material with a refractive index of 1.32 and has been widely used as a single-layer AR coating in research settings as a result , .
Thus, for each system, the refractive index must be optimized. Usually, this optimization is performed using float zone (FZ) or high quality Czochralski (CZ) silicon wafers by measuring minority carrier lifetime (τ) or surface recombination velocity , , .
The use of multiple layers of high and low refractive index creates a coating that lowers reflection across a broader wavelength range. In this context, ’high’ refers to a refractive index typically above n = 2 at 550 nm, and ’low’ is a value closer to that of glass, around 1.5.
