Photovoltaic cells remain woefully inefficient at converting sunlight into electricity . Although layered cells composed of various elements can convert more than 40 percent of (lens-concentrated) sunlight into electricity, more simple semiconducting materials such as silicon hover around 20 percent when mass-produced. And, at best, such cells could convert only a third of incoming sunlight due to physical limits. [More]
