Perovskites are cheap, abundant photovoltaic materials that some have hailed as the future of green energy.Around the world, companies are layering perovskites on top of traditional silicon to develop so-called tandem solar cells that some think could deliver at least 20% more po ... Show More

Today, solar’s dominance feels inevitable. But in 1979, when Neville Williams started promoting the industry at the Department of Energy, it felt like a far-off dream. That didn’t stop the early pioneers from thinking big and pushing the government to invest in the early technolo ... Show More

A new kind of solar cell - made by drying a special liquid on a surface - is being heralded as a revolution in solar power. The minerals known as perovskites were discovered more than 150 years ago. More recently, their crystal structure has been copied using other materials and ... Show More

As expected, 2013 was yet another record year for solar in the U.S. With 5.1 gigawatts of PV and CSP coming online, the solar industry was the second largest provider of electricity capacity behind natural gas. But how long will it continue? With a tax credit expiration looming, ... Show More
