[The State Administration for Market Regulation releases the first national standard in the perovskite photovoltaic field] On September 18, the State Administration for Market Regulation released the first national standard in the perovskite photovoltaic field, "Photovoltaic Devices Part 12: Measurement Method of Current-Voltage (I-V) Characteristics of Perovskite Photovoltaic Cells and Components", which will be officially implemented in 2027. This standard builds a scientific, reliable and generalizable perovskite photovoltaic I-V characteristic measurement method system, filling China's gaps in the field of standardized testing of emerging photovoltaic technologies. It will become a "unified yardstick" for testing and certification, product research and development, production line quality control and trade delivery, providing key technical support for the subsequent improvement of the standard system, the formulation of international standards and the industrial promotion and application of perovskite photovoltaics.
