Temperature coefficient Sample Clauses

Temperature coefficient. 1) The electrical performance test described in Sect. 4.2 shall be repeated, as a minimum, in the temperature range between 25 °C and 80 °C with intermediate temperatures at 40 °C and 60 °C. 2) Data for all electrical performance parameters at the different solar cell temperatures shall be included in the test report. 3) The temperature coefficients of short-circuit current, open circuit voltage, voltage at maximum power and maximum power shall be derived by least-square curve fitting.
