Effect of temperature on ideality factor for PERC monofacial crystalline silicon solar module

The working temperature of solar module has a significant effect on the performance. In this paper, the effect of temperature on ideality factor for PERC monofacial solar module was investigated based on single-diode equivalent circuit modelling. It is found that the ideality factor of PERC monofacial solar module decreases with the increasing temperature under different irradiances. The non-ideal behaviour can be reflected in deviation of the ideality factor from unity and its temperature dependence.
