SOLUTIONS FOR COST-EFFECTIVE SLURRY REPROCESSING IN CHINA’S SOLAR WAFER MANUFACTURING MARKET

Source: Power & Energy Solutions, Issue 24, 2014

By: W. Scott Radeker, IV

Beginning in about 2010 and continuing into 2014, the solar market in China has undergone a distinct phase shift in cost structure. This transformation has occurred as the market matures from having been largely government supported to existing as a more independent, cost-competitive, stand-alone, renewable power industry.

CAST-MONO WAFERS REVISITED: RE-EMERGENCE OF MONO TECH DRIVING WAFERING INNOVATIONS

Renewed interest in cast-mono PV cells has expanded the wafering debate beyond the standard slurry-versus-diamond-wire discussion.

Source: Solar Industry, September, 2011.

By: Nora Caley

Crystalline solar cells are no longer simply monocrystalline or multicrystalline. Now, cast-mono – or mono-like cells – are getting attention, and the methods used to develop these new cells could affect the wafering process.

A HIERARCHY OF SLURRY REPROCESSING OPTIONS

Source: TMS Conference Papers, February 14-18, 2010 – Seattle, Washington.

By: W. Scott Radeker, IV, Scott W. Cunningham

When considering the wire slicing process for cutting PV silicon wafers, recycling cutting slurry is an extremely important option to consider. There are, however, meaningful variations in recycling choices. By exploring these choices, we can help companies make effective choices. Understanding effective choices of options requires understanding the objectives which drive corporate recycling initiatives.
