Photovoltaic silicon ingots can be grown by different processes depending on the target solar cells: for monocrystalline silicon-based solar cells, the preferred choice is the Czochralski (Cz) process, while for multicrystalline silicon-based solar cells directional solidification (DS) is preferred.
The importance of crystallization methods in solar cell silicon ingot quality. The effects of the Czochralski (Cz) and directional solidification (DS) methods on microstructure and defects are reported. Challenges in monocrystalline and multicrystalline silicon ingot production are discussed.
Significant advancements over the past 50 years have enabled the production of larger ingots today. Solar-grade silicon feedstock is melted in a quartz crucible and doped with the desired concentration of acceptors (for p-type ingots, doped with Gallium) or donors (for n-type ingots, doped with phosphorus).
The typical purity standard for solar silicon feedstock is 99.9999 % or higher, which means that the total content of impurities in the feedstock is 1 ppmw or below.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
