China Issues First National Standard for Perovskite Solar Cells

Standardising I-V measurement matters because perovskite results have been hard to compare across labs and producers, which has slowed bankability and procurement decisions. A national method, backed by the industry ministry and the photovoltaic standardisation committee, gives domestic manufacturers a common benchmark and a potential template for cross-border acceptance. The open question is whether this becomes the reference other markets adopt or remains a China-specific layer that adds testing cost for exporters.
