The State Administration for Market Regulation has released the first national standard for perovskite photovoltaics. Proposed by the Ministry of Industry and Information Technology, the document, titled GB/T 6495.12—2026, outlines measurement methods for current-voltage characteristics of perovskite solar cells and modules.
The new standard will officially come into effect in 2027. It addresses challenges such as performance fluctuations under varying light and voltage conditions, as well as the lack of unified area definitions that previously made it difficult to apply traditional crystalline silicon testing methods to perovskite technology.
The regulation establishes specific requirements for testing equipment, stabilization procedures, and methods for calculating power generation efficiency. It provides both rapid measurement techniques for R&D and various quasi-steady-state testing approaches, including a ten-point fitting method for performance evaluation.
By standardizing definitions for total and aperture areas, the new rules ensure that test results from different institutions are comparable and reproducible. This framework provides a unified basis for product development, quality control in mass production, and trade delivery within the emerging photovoltaic sector.
