Abstract:

Bulk passivation with SiNx:H has been so far a barely understood effect that can only be optimized for cell production in an empirical way. In this study we determine the structural properties of SiNx:H layers and relate these to both the deposition parameters and its passivating qualities for solar cells. These structural properties, such as Si-N and Si-H bond densities, of the SiNx:H layers deposited with either N2, NH3 or ND3 and silane are measured with FTIR. We show that Si-N bond density is an important parameter governing both the bulk and surface passivation of
