PV Module Degradation: the impact of light induced degradation (LID) and how to fix it

Alison Ciesla speaks at UNSW SPREE


Light Induced Degradation (LID) is a problem where, over the 30-year life of a solar module, the exposure to sunlight makes fundamental changes in the solar cells. This reduces the available power from the module and decreases the total energy delivered by the module over its lifetime.

At UNSW, a focus of research has been to develop processes directly transferable to industry that greatly reduce LID, thereby significantly increasing the energy delivered over the lifetime of the module.

This presentation describes the problem and the solution(s) for different solar cell technologies.

Brief Bio

Alison's background is in Electrical Engineering. During her undergraduate degree she completed her final year thesis on laser doping and plated contacts for solar cells in conjunction with Suntech Power for their Pluto technology. She completed her PhD in SPREE in 2017 focused on using lasers for advancing solar cells through development of a laser doped metal-less thin silicon monolithic cell structure, laser formed anchor points for plated contact adhesion and laser hydrogenation for improving silicon cell performance. She now focuses on hydrogenation for cheaper silicon wafers and understanding and solving the degradation in commercial cells and modules.
