Understanding LeTID
Light- and elevated temperature-induced degradation (LeTID) of PV cells can have far-reaching impacts on the efficiency of modules. Alison Ciesla and Brett Hallam of the University of New South Wales argue that accelerated testing, such as that included in the forthcoming IEC standards, is critical for LeTID identification and quantification in order to manage these impacts.
Interview: “It’s all about controlling the hydrogen”
When pioneering and award-winning solar researcher Stuart Wenham passed away suddenly shortly before Christmas last year, some in the PV industry may have wondered what would become of his research into the role of hydrogen in crystalline silicon cells. His daughter, Alison Ciesla is answering that question alongside Wenham’s former team at UNSW, advancing its work into the crucial role of hydrogen in the degradation of silicon cells.
