4th Atlas/NIST Workshop on Photovoltaic Materials Durability

Scope: With intensified pricing pressure, low cost and emerging materials/technologies are increasingly used in photovoltaic (PV) module manufacturing. To respond to new challenges of durability and reliability assessment of PV materials and modules, Atlas Material Testing Technology and the National Institute of Standards and Technology (NIST) are pleased to host a two-day workshop on Photovoltaic Materials Durability for the global photovoltaic community. This workshop is distinguished from other PV conferences by its focus on weathering, measurement, and modeling of durability for materials used in solar PV applications.

The Atlas/NIST Workshop on Photovoltaic Materials Durability will feature technical presentations, a poster session, standards discussion, and a NIST facility tour. This event will allow participants to hear from and interact with industry experts ranging from material suppliers, module manufacturers, testing and certification companies to universities and national laboratories. Attendees will not only hear about advanced lifetime test methods, but will also have an opportunity to engage in open discussions on how to convert advanced research to consensus standards development.

Areas specifically addressed, but not limited to:

  • Field performance
    • New trends in observed PV failure modes
    • Field survey in different climates
    • Field backsheet degradation
    • Field performance of bifacial PV systems and building integrated PV (BIPV) systems
    • Non-destructive imaging
  • Accelerated weathering
    • Combined UV/T/RH test
    • Thermal cycling, water spray
    • Correlation between indoor and outdoor testing
    • Potential induced degradation (PID)
  • Characterization
    • Non-destructive inspection
    • Optical properties (anti-reflective and anti-soiling, etc)
    • Adhesion
    • Corrosion and acetic acid formation
    • Crack monitoring and analysis
    • Depth profiling of component degradation
    • Electrical, voltage breakdown
    • Relative thermal index (RTI) and relative thermal endurance (RTE)
  • Modeling and lifetime assessment
    • Service life prediction
    • Accelerated life testing/ Extended testing
    • Thermo-mechanical stress and strain modeling
    • Statistical modeling for Linking accelerated test to field performance
  • Development in materials, module technology and applications
  • Safety

Who should attend:

  • R&D staff interested in new materials and systems for PV
  • Technical standards participants engaged in transitioning R&D into PV standards
  • Reliability and QA personnel tasked with maximizing longevity and durability of their products (suppliers and module manufacturers)
  • Financial managers, industry executives, and concerned system owners who are interested in warranty considerations and return on investment calculations in their business models
  • Anyone interested in understanding long-term performance issues in the PV industry
