A process that reduces waste while using sound to cut materials for solar photovoltaics technology was developed by the Defect Engineering for Energy Conversion Technologies lab at ASU, directed by Mariana Bertoni, a professor in the School of Electrical, Computer and Energy Engineering, part of the Fulton Schools. The process became the basis for a venture by a Phoenix-based startup now called Crystal Sonic. The company worked with ASU to further develop the technology and obtain a patent for the process. Crystal Sonic’s target customers include semiconductor material suppliers, device manufacturers and equipment manufacturers.
