Spray-on Solar Panels

Have you seen those big, bulky, breakable photovoltaic cells that now collect the sun's rays? Well, what if solar energy could be harnessed using tiny collectors that could be spray painted on a roof, a wall or even a window?

The science of converting sunlight into electrical energy is more than a century old, but the reality of doing it efficiently and affordably is ongoing.

With support from the National Science Foundation (NSF), that's what Brian Korgel and his team are doing to create solar cells that are light, flexible, efficient and--often the biggest obstacle--affordable.With support from the National Science Foundation (NSF), that's what Korgel and his team are doing to create solar cells that are light, flexible, efficient and--often the biggest obstacle--affordable.
