light induced degredation

Don Cowan and Mahyar Mohammadnezhad of Kiwa PI Berlin explain the importance of upstream diligence in ensuring long-term PV performance.

Brian Grenko of VDE Americas assesses the route to market for perovskite PV products as an alternative to silicon-based technologies.

The US Department of Energy (DOE) has found that a “hybrid polymer material” in perovskite cells could minimise weather-based degradation.

LayTec has introduced the first commercially available system for simulation and monitoring of LID (Light Induced Degredation). ‘LID Scope’ is a table-top system that helps to quantify the expected performance loss of any solar cell directly at the production line or in the lab. The tool performs accelerated or real-life degradation tests fully automatically. It is claimed to deliver highly reproducible results and a permanent monitoring of Voc changes by integrated metrology.
