GCL System Integration Technology (GCL SI), a company under the GCL Technology Holdings clean‑energy group, together with Soochow University and Yangzhou University, recently initiated drafting group standards for testing and performance verification of 3-terminal crystalline silicon-perovskite tandem solar cells.
GCL SI said that 3-terminal perovskite tandem technology based on back-contact (BC) cells currently faces industrialization challenges due to a lack of unified testing standards, leading to poor data comparability and inconsistent performance evaluation. The proposed standards will address issues such as unique electrode configurations, spectral mismatch, and stability testing by defining testing procedures, parameter definitions, and data processing rules.
The initiative also introduces a tiered testing framework covering laboratory R&D and industrial verification, aiming to improve data credibility and support the mass production of 3-terminal tandem cells.
