Witryna1 wrz 2005 · The experimental results show that Si self-diffusivity increases with decreasing distance between the 30 Si and Si-SiO 2 interface. We propose a model in which SiO molecules generated at the interface and diffusing into SiO 2 enhance Si self-diffusion, and the simulation results fit the experimental results. Witryna6 lut 2013 · Flexible Cu(In,Ga)Se 2 (CIGS) solar cells on stainless steel foils face the problem of efficiency deterioration when iron impurities diffuse into the absorber layer. The influence of the magnetron sputtering conditions and the design of Mo-based back contacts on the property of the diffusion barrier against iron is reported here for high …
