Researchers on Wednesday published a technical paper in the journal Advanced Materials that describes a solar cell made of abundant materials with relatively high efficiency. The cell can convert 9.6 percent of solar energy into electrical energy, a 40 percent boost over current methods.
What makes this more remarkable is that while there are higher efficiency cells out there, they use rare earth metals, and other costly components… These cells are using copper, zinc, tin, and sulfur, or selenium… Elements that are far more common, and lower cost…
