Information

The basic simple cell model consists of a scalable diode model and a signal current source with temperature dependency in order to consider the temperature coefficient of the short circuit of PV cell.

The diode model used an exponential curve when forward conducting. This exponential curve is parameterized by

These parameters are determined from the characteristic of the cell, given by the diode equation and the node equation of the equivalent circuit of Fig. 3(a) of [Brkic2019] for (1) the open circuit condition and (2) the maximum power point.

  (1)  IphRef = IsdRef * (exp(moduleData.VocCellRef / m / moduleData.VtCellRef) - 1);
  (2)  IphRef = IsdRef * (exp(moduleData.VmpCellRef / m / moduleData.VtCellRef) - 1) + moduleData.ImpRef;

These two equations are evaluated in the initial equation section of this model.

The solar irradiance of the model can eithe be constant or provided by signal input. The current of current source is determined linearely dependent of irradiance.
