Is the >40% quoted efficiency real and accurate?
It is as real and accurate as we can measure it and these efficiencies have been validated by sample testing at potential clients. We have used the best available measurement equipment and we are confident that these measurements are as accurate as current technology permits. In fact we have measured cells with efficiencies of 42% but we have chosen to quote a lower number to be conservative and to be representative of the average cell capability. In any type of semiconductor production there is an inherent variability in devices produced and it is not our practice to base our efficiency claims on a few “champion cells”.
