In 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.
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 refractive index of a generic material, such as sodalime glass or silicon nitride, can vary substantially from one sample to another. This might be due to varying levels of impurities, to differences in stoichiometry, or to differences in density, which all depend on how a material is formed and treated.
From Eq. (1), we deduce nSiN = 1.96. For encapsulated cells, the refractive index of the external medium is constituted of glass and EVA. The refractive index next is approximated to 1.45. The optimal nSiN is equal to 2.37. In the present work, four refractive indices were studied.
This might be due to varying levels of impurities, to differences in stoichiometry, or to differences in density, which all depend on how a material is formed and treated. Do not expect that the refractive index provided here represents all manifestations of a material.
In addition, a film with this refractive index was found to be thermally and electrically stable. This optimization method has the advantage to use mainly experimental results. It allows the optimization of the SiN film refractive index without having to make complete solar cells. Finally, it can be used for any PECVD system.
