The Promise Of Perovskite Solar Panels

Solar holds great promise as a clean energy solution, as the sun is an incredibly abundant resource, and panels can be placed unobtrusively on roofs and in fields. And solar panel technology has advanced quite a bit over the past few decades: panels have become less expensive, more efficient, and more widely used. Panels also generally fare well, considering that they’re outside in inclement weather year after year.

Recent advancements with perovskite solar cells—a type of cell whose name refers to the structure of a compound it contains—have many clean energy enthusiasts excited. Perovskite solar cells are a thin, flexible technology that can even be painted onto a structure and conduct electricity. Much of the work on these has been conducted at the National Renewable Energy Laboratory (NREL) based in Golden, Colorado.

At Science Friday Live in Boulder, Colorado, Ira sat down with two solar experts from NREL, Dr. Joseph Berry and Dr. Laura Schelhas, to discuss perovskite solar cell advancements and the future of this clean energy technology.

Transcripts for each segment will be available after the show airs on sciencefriday.com.
