Advanced characterization and forensics of solar module materials

Seven step process diagram

Our Approach:

  1. Discuss w/ DuraMAT stakeholders, identify essential interfaces/materials for further study
  2. Source materials w/ technoeconomic value (Cap6) from DuraMAT stakeholders
  3. Characterize pristine interfaces/materials w/ advanced tools available in Cap3. All data stored by Cap1-Data Hub
  4. Stress interfaces/materials through field tests and/or accelerated aging in collaboration with Cap4 and 5, characterize and compare aged samples w/ pristine sample data
  5. Reassess, if knowledge from steps 3 + 4 fails to identify the degradation mechanism, design new/improved/advanced tools
  6. DuraMAT stakeholders use insight gained from characterization of pristine + aged samples in development of new materials, Cap2 uses data for model validation
  7. Assess results and impact, repeat cycle for further improvement or begin cycle again to identify new material/interface

Current focus areas:

  • Anti-soiling coatings
  • Encapsulant/cell interface degredation
  • Degredation by ionization damage
  • Backsheet durability
  • Accelerated testing validation
