Milpitas, Calif.-headquartered VLSI Standards Inc. has expanded its current portfolio of solar cell certification services to include ISO-17025-accredited certification of customer-supplied production cells up to 156 mm by 156 mm in size.
VLSI offers multiple traceability paths to globally recognize national metrology institutes and laboratories, including the Physikalisch Technische Bundesanstalt of Germany, the National Institute of Advanced Industrial Science and Technology of Japan, and the National Renewable Energy Laboratory (NREL) in the U.S. These new offerings from VLSI allow solar cell manufacturers to meet the metrology quality requirements of their worldwide customers, speeding penetration into international markets, VLSI says.
The company's services offer traceable measurements of production cells of short-circuit current, open circuit voltage, maximum power, cell area, spectral response (or quantum efficiency), fill factor and cell efficiency. These measurements will be conducted under standard test conditions. As an option, temperature dependence measurements are also available.
