Replace the existing second item in the dashed list in 5.1 by the following:
Relative temperature coefficients (α , β and δ ) expressed in percentage per unit

temperature (%/K or %/°C) can be determined by dividing the calculated value of temperature
coefficients α, β, and δ by the values of short-circuit current, open-circuit voltage and maximum
power respectively determined from the least squares fit at 25 °C corresponding to an irradiance
of 1 000 W/m . The relative coefficients so determined are valid at the irradiance and spectrum
at which the measurements were made. For linear PV devices with respect to irradiance
(typically the case for c-Si), the relative temperature coefficient α is valid over the entire range
