Summary / Abstract:
This work presentsthe comparison of measurement resultsfor four types of encapsulated high efficiency (HE) c-Si solar cells measured by ten laboratories based in Asia, Europe and North America utilizing a wide range of voltage sweeping methods, which include well-established procedures that represent good industry practice, as well as recently introduced ones that have not been verified yet. A proficiency test was employed to examine the consistency of results and their corresponding uncertainties. The results of all participant laboratories generally remained well within [−1; 1], thus indicating consistency between the measured values and the reference values within stated measurement uncertainties. A preliminary analysis revealed that differences remained within ±1.15% in PMAX and within ±0.35% in VOC for all participants and methods applied. Essentially this work forms the basis to validate all applied methods and their stated measurement uncertainties.
