Solar Cell Teams Plastic and Carbon
Today's solar cells are relatively expensive because they are made from the computer chip material silicon, which requires relatively expensive manufacturing processes including clean rooms.
It is possible to make solar cells from cheaper, easier-to-work-with materials, including organic, or plastic-based materials. The trick is finding inexpensive materials that are also efficient.
Researchers from the Georgia Institute of Technology have fabricated an inexpensive, plastic-based solar cell that has the potential to be fairly efficient.
