'Magic' Alloy Could Spur Next Generation of Solar Cells

In what could be a major step forward for a new generation of solar cells called "concentrator photovoltaics," University of Michigan researchers have developed a new semiconductor alloy that can capture the near-infrared light located on the leading edge of the visible light spectrum. Easier to manufacture and at least 25 percent less costly than previous formulations, it's believed to be the world's most cost-effective material that can capture near-infrared light—and is compatible with the gallium arsenide semiconductors often used in concentrator photovoltaics.

'Smart' Transformer Supports Power Grid of Tomorrow

Imagine a system that handles electricity flow not just from the power company to our homes, but also back from our homes to the power company. North Carolina State University researchers say an existing technology – the solid-state transformer — could make the conceptual "smart grid" a reality.

Smart Windows Get Smarter (and Self-Powered)

A “smart window” from Princeton University uses a transparent solar cell to selectively absorb and harvest near-ultraviolet light. The advanced window controls the transmission of visible light and infrared heat into the building, while the new type of solar cell uses near-UV light to power the system.
