In this study, the silica with special structure that rapidly dissolves in dilute alkali solutions
even at room temperature (25° C), which challenges the traditional concept of the high …

A multicrystalline silicon ingot was obtained from metallurgical-grade silicon by vacuum
induction melting and directional solidification. Based on the concentration distributions of …

The constantly rising price of silicon feedstock has been the most important factor preventing
photovoltaic (PV) energy from reaching grid parity. On the other hand, large amount of …

In this study, we performed a numerical simulation of the growth of multicrystalline silicon
ingots using the DSS method and compared the results with the experiments. The thermal …
