| Popis: | Plasma spraying of silicon powder onto an alumina substrate allows the production of self-supported ribbons having good photoelectric quality in spite of their poor microstructure and purity. In the first part of this paper, the plasma- particle interactions are modelled so as to determine the position, velocity, temperature and mass loss of a silicon particle as a function of the spraying distance; measurements of the velocity and temperature are used to validate this simulation. The second part is devoted to some local measurements of the impurity content: most impurities are found to be included in microprecipitates, leaving the silicon matrix very pure, which explains its good photoelectric quality. |
