The hottest new material in solar cell research has another trick up its sleeve. At the Materials Research Society meeting here, two groups reported yesterday that these new electricity-generating materials can produce laser light. Because the materials—called perovskites—are cheap and easy to produce, they could help engineers create a wide variety of cheap lasers that shine a variety of colors for use in speeding data flows in the telecommunications industry.
