Caption: University of Utah metallurgical engineers Prashant Sarswat and Michael Free used an old office microwave oven to produce a nanocrystal semiconductor named CZTS that is made from cheaper, less toxic materials than other semiconductors and holds promise for more efficient solar power cells and lighting by LEDs, or light-emitting diodes, as well as sensors for medical tests and systems to convert waste heat to electricity.
