Influence of the NH 3 :SiH 4 ratio and surface morphology on the surface passivation of phosphorus-diffused C-Si by PECVD SiN x

Wan, Yimao; Yan, Di; Cuevas, Andres; McIntosh, Keith


We investigate the surface passivation of phosphorus (n+) diffused crystalline silicon that is either planar or textured and passivated with amorphous silicon nitride (SiNx). A low and relatively constant saturation current density J0 is attained on the n+-diffused planar surfaces over a wide range of refractive index (n = 1.9-2.9 at 632 nm), and a wide range of sheet resistance (39-320 Ω/□). The results demonstrate that the trade-off between the optical transmission and surface recombination...[Show more]
