Groundbreaking Advances from China’s Metrology Experts
The Fujian Metrology Institute (FMI) and the National Photovoltaic Industry Measurement and Testing Center (NPVM) in China have unveiled a state-of-the-art metrological traceability system designed for solar cells made of both silicon and perovskite. This innovative calibration system incorporates advanced technology, including a **monochromatic light system**, **bias light system**, a **3D-motion measurement platform** featuring temperature control, and an **electrical measurement system**.
Existing calibration methods from prestigious institutions, such as Germany’s PTB and China’s NIM, have laid a foundation, but the new system enhances precision significantly. By adhering to the established IEC standards, researchers created a differential spectral responsivity (DSR) calibration method, achieving an impressive measurement uncertainty of only **0.7%**.
The calibration process maintains optimal conditions for accurate readings, utilizing a white bias light reflecting an irradiance range from **0.01 to 1.2 suns** and a uniform monochromatic light range from **280 nm to 1200 nm**. This allows for precise comparisons with established reference values.
By successfully integrating these systems, researchers have positioned their technology alongside global standards, confirming its robustness through international comparisons. This advancement not only boosts the efficiency of solar cell calibration but also enhances overall solar energy technology’s reliability. The insights from this research were documented in the study “The establishment of a metrological traceability system for solar cells,” published in *Measurements: Sensors*.
