Astronergy boosts mono-crystalline-silicon PV efficiency

Astronergy has improved design and manufacturing techniques for 6″ mono-crystalline silicon solar cells, exceeding 19% efficiency without raising the production cost.

October 27, 2011 — Astronergy has improved design and manufacturing techniques for 6″ mono-crystalline silicon solar cells, exceeding 19% efficiency without raising the production cost.

Astroenergy dubbed the new photovoltaics manufacturing technologies “Nova” and is commercializing new solar cells made with the process.

Varian Semiconductor Equipment Associates Inc. (NASDAQ:VSEA) partnered with Astronergy for 2 months to improve cell efficiency and simplify solar cell manufacturing process using Varian’s Solion
ion implant system.

The company will continue to make improvements, noted Dr. Liyou Yang, CEO at Astronergy, with affordability as a target. Additional efficiency improvements are enabled with the new technology and planned for production introduction in the near future.

Jim Mullin, Varian VP and GM of the Solion business unit said that his company’s will continue to work with Astronergy to ramp this process in high-volume production and for next-generation advanced cell designs.
