Nucleation in small scale multicrystalline silicon ingots

Development of high‐performance multicrystalline silicon for photovoltaic industry

“…Unfortunately, keeping a large undercooling was not easy even with a rapid cooling in a small crucible. In a recent paper by Brynjulfsen et al [31], four experiments were carried out with a similar growth setting. One growth had an undercooling of about 10 K, but the other three did not have a significant undercooling for the high crucible pulling rate up to 300 cm/h.…”

The impact of oxygen precipitation on dislocation generation at small angle grain boundaries during seed‐assisted directional solidification of silicon

“…The solidification method is described in Refs. . The solidification process can be described as follows: Step 1 of the process corresponds to the ingot pulling, i.e., when directional solidification occurs.…”

“…The solidification method is described in Refs. [15,18]. The solidification process can be described as follows: rates have been selected, namely 3 mm s À1 (ingot I 1 ) and 13 mm s À1 (ingot I 2 ).…”

Report on use of Inoculants in Missile Application Alloys

“…The resulting microstructure provided significantly improved mechanical properties (1890 MPa fracture stress and 14% plastic strain) in comparison with the base BMGC (1560 MPa fracture strength and 7.5% plastic strain) through manipulation of the TRIP-effect enabled through ZrCu-B2 distribution. Researchers have also used inoculants to create Si3N4 precipitates in solar sell Si materials [157], and nanosize Y2O3 powder additions in HEAs to form core-shell structures [158]. Even Sn solders have been inoculated to promote beta-Sn nucleation in near eutectic Sn-Ag-Cu solders as a strategy for avoiding development of unwanted microconstituents [159].…”
