Latest solar cells Stories
Throughout decades of research on solar cells, one formula has been considered an absolute limit to the efficiency of such devices in converting sunlight into electricity: Called the Shockley-Queisser efficiency limit, it posits that the ultimate conversion efficiency can never exceed 34 percent for a single optimized semiconductor junction.
Stanford University and the Department of Energy’s National Renewable Energy Laboratory have developed a peel-and-stick solar cell that could one day be used to charge mobile phones and power a variety of other small devices.
Nanowires could be the answer for constructing solar panels with less materials and lower costs.
A recently added market report by Transparency Market Research on “Thin Film Photovoltaics Market - Global Industry Size, Market Share, Trends, Analysis And Forecasts 2012 - 2018" is now
Researchers have developed recyclable, efficient solar cells using natural substrates from plants like trees. When these solar cells reach the end of their life, they can be easily degraded in water.
Extremely tiny nanowires are expected to revolutionize the field of electronics, and a new study in the journal Nature Photonics shows that they could have an impact on solar energy production as well.
Since the seventh century B.C., mankind has looked to the power of the sun to provide an energy source. In the earliest days, humans used glass and mirrors to concentrate the sun's rays to make fire. Later, around the first century A.D., the Romans discovered large south facing windows could help let in the sun’s warmth.
