(PhysOrg.com) -- Solar cells could make fossil fuels virtually redundant if they were cheaper, but their use of rare elements and complex manufacturing processes makes them expensive. Now IBM Research has developed a prototype solar cell that solves both problems, using common, cheap elements and using an inexpensive manufacturing process. Their paper is published in the Advanced Materials journal.
