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 Isc and the open-circuit voltage Voc, are performed and series resistance of cells is determined. An extrapolation procedure is used to correct the output parameters to STC
