The establishment of a metrological traceability system for solar cells

The construction of measuring capabilities for primary reference solar cells and measurement services for mass-produced photovoltaic products are usually offered by national metrology institutes and market-oriented institutions respectively. As a result, there are problems such as broken traceability chains, inconsistent measuring capabilities, and inaccurate measurement results. In order to better serve the photovoltaic industry, Fujian Metrology Institute (FMI)/National Photovoltaic Industry Measurement and Testing Center (NPVM) has established for the first time in the world a complete and accurate metrological traceability system from the primary reference solar cells to the silicon solar cells and the perovskite solar cells. Herein, we will introduce the main work of establishing the photovoltaic traceability system and its application effects.
