solar cells

Four American teachers have been stabbed in China. Here’s what we learned about how it happened and how they’re doing.

The National Renewable Energy Laboratory this week said that rooftop solar panels have the potential to generate nearly 40 percent of electricity in the U.S. But what about the cost of going solar?

The process easily assimilates to existing high volume manufacturing production lines.

Every time you stroll outside you emit energy into the universe. Heat from the top of your head radiates into space as infrared light.

Solar cells capture up to 40 percent more energy when they can track the sun across the sky, but conventional, motorized trackers are too heavy and bulky for pitched rooftops and vehicle surfaces.

Nanowires made of zinc oxide are highly anelastic—meaning they return to shape slowly after being bent, rather that snapping right back.

Whenever I tell people I work with solar cells I am asked the same two questions: are they ever going to be really cheap? And can you get me some?
