Abstract

This paper describes the measurement techniques used for the calibration of the Newer Technology reference solar 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 α and β as well as the curve correction factor κ 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 STC
