National Standardization Administration of China

The State Administration for Market Regulation/National Standards Committee released the first national standard for perovskite solar cells, GB/T 6495.12-2026, detailing current-voltage measurement methods and to be implemented in 2027. The standard aims to unify testing for perovskite cells and modules, addressing stability concerns under light and voltage, and provides methods for rapid, quasi-steady, and MPPT testing to ensure fair, comparable results across laboratories and production scales.
