Halvard Haug on "Efficiency, lifetime and degradation of silicon solar cells and modules - a story from microseconds to decades"
Welcome to a lunch talk with associate professor, Halvard Haug!
The efficiency of silicon solar cells is highly dependent on recombination active defects in the silicon material. It is well known in the industry that these defects in some cases can become more or less detrimental over time when the cell is exposed to light, causing an interesting connection between the material properties and the energy production in the field. How do we robustly measure degradation in solar power plants, and can we explain the observed degradation using fundamental physical processes?
