What is Repeatability?
Repeatability is one of the most critical factors of the measurement capability of an equipment. In general, the sample will be tested several times, and the result will be calculated from those data thus generate a repeatability, which is shown in percentage. Repeatability shows the stability of the equipment, ensuring every test result is precise without being affected by the environmental noise. Enlitech’s QE/IPCE measurement system has outstanding performances both in stability and repeatability exceeding 99.5%, and has been acknowledged and approved by many leading research centers and solar cell manufacturers.
