What if everything around you had the potential to generate small amounts of energy?
We've seen flexible, even stick-on photovoltaic cells before, but these decal-style solars are compact and fun.
In a recent article in Scientific Reports, Stanford University mechanical engineering assistant professor Xiaolin Zheng and colleagues describe thin-film solar cells that can be peeled and stuck anywhere.
The researchers manufactured them on a reusable silicon and silicon dioxide wafer and then stuck them on paper, plastic, and window glass.
The original cell efficiency of 7.5 percent was maintained, and the manufacturing uses existing processes and materials. That … Read more
