With a $4.8 million award from the SunShot Initiative, Gloucester, Mass.-based Varian Semiconductor is developing a tool that manufactures
interdigitated back-contact solar cells with ion-implanting technology. Featured above is a close-up of the tool.

Researchers at PPG Industries prepare glass samples for accelerated exposure testing for a new encapsulant for cadmium telluride (Cd Te) thin-film solar modules. The end product will combine transparent
conducting oxide glass substrate with an anti-reflective coating.

At 1366 Technologies, Frank van Mierlo, right, and fellow co-founder Emanuel Sachs, middle, are working
to commercialize their Direct Wafer silicon wafer manufacturing process. By pulling wafers directly from
the silicon melt, the technology halves the need for hyper-pure silicon. At left is Carmichael Roberts,
chairman of the 1366 Technologies Board.
