With its two chief properties of excellent electrical conductivity and optical transparency, indium tin oxide (ITO) can be found in transparent conductive coatings for displays found in all... Read more
Solar cells could become more efficient and less expensive, thanks to the development of tapered nanopillar semiconductors that are narrow at the top and wide at the bottom. Created by chemi... Read more
Imagine if all the windows of a building, and perhaps even all its exterior walls, could be put to use as solar collectors. Soon, you may not have to imagine it, as the Norweigan solar power... Read more
Traditionally, the goal of high power conversion efficiency in thin film solar cells has been compromised by opposing optical and electrical constraints – while a cell needs to be thi... Read more
Japanese scientists are celebrating the successful deployment of their solar sail, Ikaros. The 200-sq-m (2,100-sq-ft) membrane is attached to a small disc-shaped spacecraft that was put in o... Read more
When most people think of solar cells they picture the rigid glass panels that dot rooftops around the world. But the solar cells of the future will be much more adaptable, with researchers... Read more
Image via Wikipedia Some argue that major technical breakthroughs are needed to make electricity from sunshine cheap. Are they right? Do the photovoltaics that can transform sunshine into el... Read more
Image via CrunchBase Here’s how to make a solar cell from silicon: take one solid block of doped silicon, saw it into thin wafers, layer said semiconductors beneath a panel of transpar... Read more
Enough sunlight bathes Earth’s daytime half in an hour to meet all human energy needs for a year. Sadly, there are several problems with meeting human energy demands by tapping such ab... Read more
