This air-breathing solar panel stores its own electricity, cutting the cost of solar power significantly

It's a solar cell! No... it's a rechargeable lithium-air battery! No... wait... it's both: It's the world's first all-in-one solar battery! This is significant, because one of the biggest problems with wide-scale solar power deployment is that you also need huge banks of batteries to store electricity. An integrated solution is both cheaper and more efficient -- about 25% cheaper and 20% more efficient, according to the researchers.
