The temperature coefficient of a solar cell is the amount by which its output voltage, current, or power changes due to a physical change in the ambient temperature conditions surrounding it, and before the array has begun to warm up.
In a solar cell, the parameter most affected by an increase in temperature is the open-circuit voltage. The impact of increasing temperature is shown in the figure below. The effect of temperature on the IV characteristics of a solar cell. The open-circuit voltage decreases with temperature because of the temperature dependence of I 0.
a variety of “effective” temperature coefficients for of commercially available photovoltaic modules. In the table, the units for the temperature coefficients have been normalized to 1PC by dividing the coefficient by the value for the parameter at ASTM Standard Reporting Conditions (1000 W/m2, AM=1.5, 25 The normalized coefficients “C).
The cells are illuminated with the solar simulator, and subsequent current–voltage (I-V) curves are measured over a range of cell temperatures (King et al., 1997, Tayyib et al., 2014, Dubey et al., 2015). The module temperature should be stable within ± 2 °C before the measurement routine, and the range of temperatures should span at least 30 °C.
This result demonstrates that there exist opportunities to tune the temperature coefficients of solar cells and optimize their designs at their operating temperature instead of at 25 °C (which is the temperature prescribed in the standard test conditions, see Sect. 3.5).
The temperature of the photovoltaic cell and the irradiance are measured simultaneously with the I-V characteristics. The accuracy of the temperature measurement is ±0.5°C, and the accuracy of the irradiance is ±3 W/m 2.
