Solar silicon manufacturing innovators get big boosts with new DOE loan guarantees

By / June 20, 2011

Calisolar silicon is purified in a unique, liquid-phase process producing solar silicon without the high energy and specialized equipment of conventional vapor-phase silicon purification.

1366 Technologies demonstrates directly manufactured silicon PV wafer

By / March 9, 2010

Last August I wrote about the typical 50% waste created when wire saws are used to slice silicon ingots into PV-suitable wafers, and research being conducted in Germany to lower that waste. Now 1366 Technologies, according to a story and video by Technology Review’s Kevin Bullis, is saying it might be able eliminate all saw…

Cutting PV costs, Part 2: Process improvements vs. science breakthroughs

By / September 24, 2009

Yesterday we posted a Technology Review video interview with Emanuel Sachs (1366 Technologies’ chief technology officer and professor of mechanical engineering at MIT) in which he and Craig Lund (1366’s director of business development) discuss some of the new technologies the company is incorporating into PV panels. Sachs did what I think is a very…

Cutting PV costs, Part 1: New busbars, ‘fingers’ to cut costs by 20%?

By / September 23, 2009

Technology Review has a video (24 min.) of a recent interview with Emanuel Sachs, 1366 Technologies’ chief technology officer and professor of mechanical engineering at MIT. He explains the physics of solar cells and how 1366 is using the techniques described below to try to make them more efficient. (Note, there is a brief sponsor…
