Abstract: Photovoltaic (PV) power generation is one of the most promising renewable and clean energy technologies, and China has become the world's largest producer, user, and exporter of photovoltaic products. Accurate and reliable measurement of the photoelectric performance parameters of PV products is critical for their scientific research and industrial development. Based on the traceability and dissemination system established by the National Institute of Metrology, China (NIM), China's photovoltaic industry has achieved effective traceability and dissemination of key quantities. This article reviews the research and establishment of the traceability and dissemination chain for China's photovoltaic industry, from the highest relevant standard, the cryogenic radiometer, to terminal PV products, and provides prospects for the next stage of research.
