Weekly News Update: “Solar Cell Defect Mystery Solved After Decades of Effort”, The University of Manchester
Friday June 7, 2019
An article posted on the University of Manchester’s website reports that a team of scientists at the University have solved the initial degradation of solar cell efficiency. Prof Tony Peaker explains that “during the first hours of operation, after installation, a solar panel’s efficiency drops [around 2%]”, a phenomenon known as LID (light induced degradation). The experimental and theoretical approach taken by the researchers has identified the mechanism responsible for LID. The research has uncovered the “existence of a material defect which initially lies dormant within the silicon used to manufacture the cells”.
