Want to light up Niagara Falls for St. Patrick’s Day? Green LEDs, the most efficient source of light, aren’t easy to make – but new perovskite materials may change that.
Solar panels are expensive because of the high-purity silicon present in them. A new material called perovskite rivals the solar conversion efficiency of silicon, but at a fraction of the cost. There is however still a lot of fundamental understanding to be done on perovskites, which these researchers do by studying analogous structures.
Lasers are cool – everyone who’s seen a sci-fi movie knows that. But we still haven’t figured out how to use them to their full potential in real life. This paper explores some ways to improve the efficiency of quantum dot lasers, which have a myriad of applications in computers to cell imaging.
