Photovoltaic Technology - PV Si Feedstock Evaluation
PV Si feedstock refers to the solid silicon that is fed into furnaces that make either rectangular blocks of multi-crystalline Si, cylindrical boules of single crystal Si, or Si ribbon, which are then “shaped” into Si wafers for Si solar cell manufacturing.

"The specific elemental impurities that need to be evaluated in feedstock depends, to some extent, upon the process to make the solar wafer and the solar cell design and processing."
