This paper describes the measurement techniques used for the calibration of the Newer Technology reference cells for the 3rd PEP round robin, held from 1993 to 1995. The current-voltage characteristics of the devices under test are not only measured close to Standard Test Conditions (STC), but also at a number of different temperatures, allowing the temperature coefficients alpha and beta as well as the curve correction factor kappa to be established. Linearity measurements with respect to the short-circuit current I(sc) and the open-circuit voltage V(oc) are performed and series resistance of cells is determined. An extrapolation procedure is used to correct the output parameters to Standard Test Conditions.
