Using ultrasonic irradiation to separate backsheets in PV waste
Chinese researchers have used an industrial-grade, 720 W ultrasonic cleaner – with a frequency rating of 28 Khz and 1,000 W of heating power – to separate backsheets from end-of-life PV modules. They’ve concluded that an ultrasonic power of 720 W is ideal for the separation process.
Scientists from East China University of Science and Technology claim to have developed a new process to separate backsheets from end-of-life PV modules for recycling purposes.
