Establishing CIGS-specific capabilities for regional and customer-sited testing
Testing arrays under multi-regional and real-world conditions is critical for (1) providing design cycle data to manufacturers, (2) ensuring that predictive performance tools accurately account for enhanced properties of CIGS modules, such as low light level and shading performance, and (3) providing stakeholders with validated outdoor performance data.
The Outdoor Performance project is building test arrays comprised of CIGS modules from various manufacturers and comparing measured performance to predicted performance. Predictive tools used by the industry today are not necessarily optimized for CIGS PV arrays; one of the goals of this project is to improve the capability of these tools for CIGS analysis.
The Outdoor Performance project has capacity for installing and monitoring ground-mounted, rooftop, and tracker-enabled systems and is closely tied with the Indoor Accelerated Lifetime Testing to correlate outdoor testing results to indoor testing.
Identifying failure mechanisms and developing models to estimate lifetime
PVMC is working closely with the CIGS industry to identify a set of protocols for indoor accelerated testing to identify and replicate field failures by simulating outdoor stress conditions. The main objective of the IALT project are to
