Reliability, Recycling, and Reuse of PV Modules
Reducing the cost of solar electricity requires more than improving efficiency. Extending the lifetime of PV modules and limiting wear and degradation are equally important. That is why reliability is a central focus of EnergyVille’s research activities.
Reliability Research for Next-Generation PV Modules
At EnergyVille, we conduct in-depth research on the reliability of materials and technologies for next-generation PV modules.
In addition to applying established test methods, we develop new testing procedures and actively contribute to the creation of future industry standards.
We design targeted reliability studies to identify weaknesses in materials and technologies. By combining opto-electrical characterisation with destructive material analysis, we can uncover underlying defects and failure mechanisms.
Advanced Reliability Testing
Our research is supported by extensive testing infrastructure.
-
We use climate chambers to perform accelerated reliability tests, including thermal cycling, humidity testing and damp heat testing.
-
These tests can be combined with UV exposure to better replicate real-world operating conditions.
-
For applications where appearance is important, we also assess colour stability across individual modules and between different modules.
Understanding Degradation Mechanisms
EnergyVille has extensive expertise in investigating and analysing the degradation mechanisms that affect PV module performance.
These include:
-
PID (Potential-Induced Degradation)
-
LID (Light-Induced Degradation)
-
LeTID (Light and Elevated Temperature-Induced Degradation)
Understanding these mechanisms helps us develop more reliable materials, components and module designs.
Designing for Recycling and Reuse
Reliability also plays a key role in reducing the environmental footprint of solar energy. Our research focuses on technology designs and material choices that improve recyclability and reduce or eliminate the use of toxic materials. At the same time, we investigate ways to extend the operational lifetime of PV modules and support their repair, refurbishment and reuse.
Towards More Sustainable Solar Energy
By improving reliability, facilitating recycling and encouraging reuse, we help reduce the environmental impact of PV systems throughout their entire lifecycle. This contributes to a more sustainable and circular solar energy sector.
